Check out the answers to frequently asked questions in different topic areas:
Ordering, Delivery, and Invoicing
OFFER CALCULATION AND PRICING
I would like an offer; how should I proceed?
Send an email to email@example.com and provide the quantities and your needs. Attach technical drawings of the parts for which you want an offer. We aim to respond to you as quickly as possible.
There is some ambiguity in the offer, what should I do?
How do you determine pricing?
This is a trade secret, but we can provide some insight. We calculate the material, machine time, and setup time, which typically form the basis of the price for a single item. We do not have a minimum order quantity, but in practice, the startup costs (order reception, nesting process, production scheduling, setup times, internal logistics, material collecting, packaging, and invoicing) need to be considered in addition to machine time and material.
How can we get the price per unit as low as possible?
We always offer the best price based on the needs and the flexibility allowed by the customer. Generally, the unit price for batches corresponding to the number of units produced from a sheet or multiples of sheets is the most cost-effective. Additionally, we hope to deliver all the produced pieces and not a specific quantity. Each order is entered into the system, part are nested, part flow is scheduled into production, has machine setup time and work time, and any additional work steps. When the work is completed, the product is picked, packaged, and invoiced. This process repeats regardless of the quantity. Therefore, it is more cost-effective to order in larger than smaller batches. We have hundreds of satisfied customers over the years who return again and again. This indicates that our cost level has been suitable for many. Our customer satisfaction rating is 4.7/5, which is an important measure for us.
How do I place orders with Stremet?
Orders can be submitted to the email address firstname.lastname@example.org. Orders are primarily made using a PDF attachment that includes all the necessary information for ordering and delivery.
How is an order placed?
Specify the desired items, quantities, any surface treatments, delivery method, and include technical drawings of the parts (DXF, DWG, or STEP) along with a PDF image. Ensure that the drawings provide sufficient information for the work, such as thickness, material, and dimensions.
Do you have any minimum order quantities or other conditions?
No, we do not. All orders are equally important. We aim to minimize material waste, so we prefer to process a whole sheet at once and invoice for the entire sheet. Therefore, it’s advisable to plan your order based on sheets to keep the unit price as low as possible. Our smallest sheet size is 1000 x 2000 mm.
Can I place consolidated orders with different delivery dates?
Yes, that’s possible and even preferable. If the dates are close to each other, it allows us to process the parts together. However, we always deliver the parts according to the requested dates and do not combine orders without prior agreement.
Under what items do I place orders?
We use the customer’s items, item codes, and identifiers. When you place an order for the first time, we store the item under a code you provide in our system. The code will be ready for your next order.
How do you manage revisions?
We aim for the customer to manage revisions, as we are merely a subcontractor responsible for production. We appreciate it when drawings clearly indicate and name the code that distinguishes it from the previous revision. This is important as drawings are stored electronically.
What if I’ve never ordered before?
Send an email to email@example.com and place the order. Additionally, provide your invoicing details so that we can set up an account for you.
What information is needed to begin a customer relationship?
Delivery address, invoicing address, contact person, and account information. Also, provide transportation details from your freight agreement.
How are invoices sent?
We use electronic invoicing. Invoices are generated from the Lemonsoft ERP system.
How is the payment term determined?
Typically, the payment term is 14 days unless otherwise agreed with the customer during the sales phase.
How are orders packaged?
We package orders in small packages, on power pallets, euro pallets, or long pallets. There’s protective cardboard at the bottom of the packaging. Typically, there’s a collar pallet around the packaging to prevent damage. Small quantities are packaged without a collar, as well as long parts. Additionally, special-sized packages are available upon request from the customer.
How is packaging determined?
Packaging is determined based on the number of parts to be packed, their size, and the shipping method.
Small parts and small quantities are often sent in small packages, which are 30 x 40 x 30 cm cardboard boxes. Larger quantities of small parts are shipped on power pallets with collars, or on euro pallets with multiple collars. The longest parts (over 1200 mm) are packed on long pallets. Customers can specify their desired packaging method during the order phase. If no packaging method is specified, we determine it ourselves during order collection.
What freight is used for shipping orders?
Primarily, orders are shipped using the freight and transport conditions specified by the customer. If freight details are not provided, we arrange the transportation and bill the customer accordingly.
Quality, Delivery Capability, and Complaints
How do I know what you are capable of producing?
How is the quality of the parts ensured?
With clear drawings that provide precise dimensions and manufacturing instructions and are missing no relevant information. The rest is up to us, and we are highly skilled in the production of sheet metal parts.
Which standard is used?
We use the standard specified in the customer’s drawings whenever possible. If no standard is specified in the drawings by the customer, we always use the ISO 2768-m standard. Read more about the standard here.
How are complaints arising during transportation addressed?
With the packaging instructions provided by the customer in advance. The packaging is adequate, but if there are special requirements for the parts in each order that have not been mentioned, it can affect the occurrence of complaints. We aim to be a professional subcontracting factory, but too often we are left to guess together. We hope that the absence of information won’t penalize the subcontractor.
What if I don’t have packaging instructions?
We ship dozens of shipments daily, and we have an established method of packaging shipments when packaging instructions are missing. This established method is generally accepted and works well. If there are special requirements for a product, please inform us in advance.
DAMAGE DURING TRANSPORTATION
After transportation, I noticed that some of the parts were not in good condition.
We always handle complaints without delay and ask for additional information if necessary. If the packaging method needs to be changed, we appreciate receiving this information from the customer immediately. We prefer a packaging instruction in PDF format, including text and images. The PDF will be saved under the item in our system, so the new packaging method will be followed from the next order.
I was not satisfied with the parts, what should I do?
Send your complaint to firstname.lastname@example.org
How quickly will I receive replacement parts?
We strive to avoid significant errors that would require the parts to be remanufactured. However, if a mistake does occur, we first review the order, drawings, and instructions received from the customer. After that, a decision is made on how to proceed. If the mistake is clearly on Stremet’s side, new parts will be put into production immediately, and delivery is typically very fast.
What materials and thicknesses do you have in stock?
Our most common materials typically range from 0.5 mm to 6 mm. You can review our inventory list here for more details.
How quickly can you deliver parts?
It depends on the work. Straight parts produced with our punch presses; we can typically deliver to the customer within the same week. Bent parts without painting we aim to deliver in about a week, and painted parts in approximately three weeks. However, situations can vary significantly, so the delivery time is always confirmed separately when placing an order. We strive to be a fast supplier and intend to maintain that reputation. Speed is an important aspect of our competitiveness.
What is the basis for your delivery speed?
We have a large material inventory, allowing us to start working on the sheet immediately. We have over ten punch presses and more than 20 bending machines. As a result, there is usually ample capacity available. We operate two shifts from Monday to Friday. We have extra capacity in both personnel and machinery. This enables us to quickly adjust our level of total production as needed. Our expertise and operational practices are efficient and rapid, setting us apart from many other players in the market.
What is a typical job on a punch press?
A punch press mechanically processes materials by punching, so we primarily work with materials ranging from 0.5 mm to 4 mm. Defining a typical job is challenging, as we, as subcontractors, are accustomed to handling a wide range of tasks.
What is a typical batch size?
From single pieces to batches of up to 10,000 pieces. We have separate machines for different batch sizes, ensuring cost-effectiveness. We have manual machines for small batches and automatic machines for larger batches. An economical batch size is a full sheet.
What types of tools do you have in stock?
Stremet specializes in piercing, and we have one of the largest tool selections in Finland. We have a wide range of standard and special tools. This enables us to often start work on orders, including special ones, immediately upon receiving it.
Do you pierce plastic as well?
Yes. Please read on the specifics of piercing plastic here.
Do you also punch copper?
Yes. We also have copper in stock. If the shape of the part needs to be more rounded, we cut copper using a laser cutter. For more details about working with copper, please see here.
What kinds of special tools do you have?
Threading, cupping, forming, and cluster tools, among others. We have a variety of tools suitable for different tasks. Often, we can find a suitable tool and start the job right away. If we don’t have a tool, we can obtain one from a tool supplier on a few days’ notice.
What kind of laser cutting machinery do you have?
We have two flying optics fibre lasers on-site as well as a combination machine equipped with a robot. You can find more detailed information about laser cutting here.
Do you cut copper?
Yes, up to 6 mm. For more details, please see here.
What materials do you cut?
We can cut up to 20 mm of black steel, 12 mm of stainless steel, 10 mm of aluminium, and 6 mm of copper as needed. We primarily cut galvanized materials ranging from 1 mm to 6 mm.
What is your capacity for laser cutting?
We have three machines, all equipped with automatic loading and unloading. We’ve yet to receive an order large enough to exhaust our capacity.
What is the cutting speed of your machines?
Our machines are fast. Being a sheet metal subcontractor, we can only work with competitive machines. Our fibre lasers are from 2020, 2021, and 2022.
What is your design capability?
We can offer design for manufacturability on a project-by-project basis. We use SolidWorks or AutoCAD software for drawing. You can learn more about our design services here.
Can I send you a ready-made nests for parts?
Yes and no. Typically, the nesting configuration changes in any case, so we usually must create a new nests. However, there’s an advantage to providing a ready-made nests– we can see how you’ve positioned the parts and how many fit on a sheet. This helps our nesting programmers in their design work.
What nesting software do you use?
JetCAM and NCExpress.
What do you weld?
We perform manual MIG and TIG welding. We outsource larger robotic welding series to our subcontractors. We had extensive collaboration with them in the “Lämpöä Ukrainaan” (“Warmth for Ukraine”) campaign for manufacturing stoves. Learn more about our welding services here.
Do you have tube laser cutting capabilities?
We don’t have tube laser cutting capabilities ourselves, but we can source tube parts through partners, as well as plasma and waterjet cutting.
What experience do you have with assemblies?
We handle simple assemblies ourselves. Our associate company, Manutec Oy, located in the same facility, handles more complex assemblies. We perform a lot of assembly work for various machine frames. Read more about it here.
BENDING WITH PRESS BRAKES
What can you bend, in terms of sizes and thicknesses?
All types of materials up to 3600 mm in length. Our machinery includes a range of press brakes, with the longest being 3600 mm and the shortest 500 mm. We mainly work with sheet metal thicknesses between 0.5 mm and 6 mm. Thicker pieces can also be bended if they are shorter than a metre. Learn more about bending here.
How many pieces can you produce in a day?
If the average bending speed were 500 bends per hour, theoretically, with 20 press brake machines working around the clock in three shifts, we could produce 240,000 bends in 24 hours. For basic parts requiring four bends, this would translate to 60,000 finished pieces in a day.
What types of machines do you have?
Our stock of machinery is extensive. We have hydraulic Amada machines, servo-driven Prima Power machines, and short Coastone machines. Additionally, we have two robotic press brake cells and two automated bending machines, one of which is robotic.
Do you have suitable machinery for panels?
Yes, we have two automated bending machines. The typical cycle time for a panel piece is around one minute per piece. This means we can produce 60 pieces per hour and 600 packaged pieces in 10 hours.
What is the ideal batch size for you?
All batch sizes work for us. We have specific machines for every batch size. Automated bending machines and robots are used for recurring batches of over 100 pieces.
What lengths and thicknesses can be mangled?
The maximum billet width for mangling is 2050 mm, and the maximum material thickness is 7 mm for steel. Learn more about mangling here.
What types of R-diameters can be achieved through mangling?
Our typical mangling work involves mangling pierced or laser-cut pillar stoves. Mangling of thicker material is also possible, for example to create various types of containers. Mangling is also suitable for producing different curved chain guards.
What types of inserts do you have?
We have nearly all types of inserts that can be used in sheet metal. If the required insert is not available on the shelf at that moment, we can order it while the billet is being manufactured. Learn more about inserts here.
What can be spot welded?
We typically use spot welding for connecting ventilation products, such as pipe-like duct connections in air distribution boxes and ceiling frames. Additionally, we have expertise with various air grilles and piping components. Learn more about spot welding here.
What machining services do you provide?
We offer comprehensive machining services to our customers through Hallivuori Oy, which operates within our premises. Learn more about machining services here.
How can I request an offer for machining parts?
You can send an offer request to the email address email@example.com. Stremet will provide pricing for the parts that involve both machining and sheet metal work in the same part. Hallivuori will provide pricing for parts that exclusively require machining. We offer an all-in-one service from a single source. We can also handle welding, assembly, painting, machining, and sheet metal work for your parts. If the schedule permits, we can even deliver the parts in the same shipment.
How does invoicing work if I order both types of parts?
Invoicing will come from two separate sources. Sheet metal parts will be invoiced by Stremet, and machined parts will be invoiced by Hallivuori. The customer benefits from a single shipment, if possible due to scheduling. Additionally, there is the advantage of receiving the entire order from a single source, including assembly, painting, welding, and machining.
What does storage mean? Can I store products with you?
We have provided a service for customers who can commit to giving us forecasts and a commitment to purchase the stored parts. Typically, such a customer orders regularly (several times a month) and in large quantities (hundreds of pieces at a time). In practice, the customer provides a forecast for a three-month period in advance and commits to purchasing the agreed-upon quantity of parts. We produce parts based on the forecast in our production, rather than based on individual orders. This gives us flexibility in production and provides the customer with 100% delivery reliability and a very short lead time. Read more about our storage service here.
SURFACE TREATMENTS – PAINTING
How large quantities can you paint per day?
Our powder coating line is automatic and can run around the clock as needed. Finished coated surface is produced at a rate of several meters per minute. For example, in the case of panel size of 1 x 1 meter, there could be approximately 300 pieces per hour. Learn more about painting here.
What colour options are available in powder coating?
All RAL colours are available. We have about a hundred different shades in stock, and additional colours can be ordered upon request.
Can you paint special effect paints? What about textured finishes?
Yes, we can paint both special effect paints and textured finishes. Paint is ordered separately when the order is received, so the lead time may be slightly longer.
Can you perform wet painting as well?
Yes, we can arrange wet painting as a subcontracted service.
Is galvanizing possible?
Yes. Learn more about surface treatments here.
What does galvanizing cost?
The minimum price for galvanization is 80 euros + shipping costs.
Do you have your own galvanizing facility?
No, we collaborate with Piiroinen Oy, which manufactures furniture among other things. We subcontract galvanizing, anodizing, and copper plating from them.
How long does anodizing take?
The subcontracting phase of anodizing takes about a week. Therefore, the whole order takes the normal lead time + one week.
How are surface defects detected?
The sheet must not have streaks or large scratches. The professionals at Piiroinen know how to manage the entire process to prevent surface defects. The customer’s packaging instructions are crucial to ensure that the delicate surface is not damaged during transportation.
Environment and Sustainability
Do you have an ISO 14001 environmental certification?
We are not certified. However, our operations are ready for certification based on the previous audit.
Do you provide material certificates?
We can provide a material certificate for the raw material upon request.
We can assure you that we do not use metals referred to as conflict minerals in our products. We are committed to responsible practices following the principles of the UN Global Compact.
What is the raw material waste percentage?
This is a trade secret that we do not disclose. Our goal is to minimize waste as much as possible. This reduces the price for the customer and enhances customer satisfaction. We recycle all raw material waste with 100% efficiency.
