Do you have a question about our production capabilities, materials, maximum dimensions, or working methods? Below you will find answers to frequently asked questions about Delwi Groenink Machinefabriek. Is your question not listed? Then please feel free to contact us.
What work can Delwi Groenink perform?
Delwi Groenink has multiple disciplines under one roof: (re-)engineering, sheet metal working, machining, certified welding, coating, and assembly. This enables us to handle a single specific operation as well as serial production and complete production processes.
Can I also engage Delwi for one specific operation?
Yes. You do not have to outsource the entire production process to Delwi. You can also engage us for one specific production step, such as laser cutting, sawing, CNC milling, CNC turning, welding, blasting, powder coating, or assembly.
We also have extensive production capacity for large-scale coating work.
Can you produce a complete product for us?
Yes. Because various disciplines come together within our own organization, we can handle the entire process: from engineering and metalworking to welding, coating, and assembly. We tailor the production steps we perform to your product, specifications, and wishes.
Do you produce single pieces or also series?
Both. Delwi produces single pieces and custom work, as well as small and large series. For each request, we determine which production method is most efficient for the desired product and quantities.
Does Delwi also work for private individuals?
No. Delwi Groenink focuses on business clients and does not supply directly to private individuals or consumers.
Does Delwi carry out work on location?
No. Our production activities are carried out in our own machine factory in Enschede.
Can Delwi offer input if my design is not yet production-ready?
Yes. Our engineers can optimize supplied designs and engineering documents and adapt them to our manufacturing process: re-engineering. In doing so, we consider factors such as manufacturability, material usage, production method, cost efficiency, and integration with the subsequent production process.
Can I include a technical drawing with my application?
We would be happy to. A technical drawing, 3D file, and additional product specifications will help us properly assess your request. If possible, please also include the desired material, quantities, dimensions, and required processing.
Can I request a quote?
Yes. Send us your request with as much relevant information as possible, such as drawings or 3D files, material, dimensions, quantities, and desired modifications. Based on this, we will assess the request and contact you.
Request a quote via the contact form or email to xander@delwi.nl (cc: werkvoorvooring@delwi.nl and joost@delwi.nl).
How quickly can Delwi provide a price?
That depends on the size, complexity, and type of request. We can generally assess a simple request faster than a large product requiring multiple disciplines or production steps. The more complete the technical information accompanying the request, the more efficiently we can assess it.
What is the delivery time?
The delivery time depends on, among other things, the scope of the order, required processing, material availability, and our current production schedule. We will inform you of the expected delivery time upon a concrete request. Stated delivery times apply in accordance with the applicable Metaalunie Conditions 2025.
Which materials does Delwi process?
Delwi processes steel. The exact possibilities depend on the product, the dimensions, and the desired processing. Please preferably include the material type, technical drawing, and product specifications with your request so that we can assess what is possible.
Does Delwi also process aluminium or stainless steel?
No. We focus our production on steel and do not process aluminum or stainless steel.
Does Delwi provide certified welding?
Yes. Delwi can perform certified welding. Does your product or construction have specific requirements regarding welding or certification? Please mention these in your request so that we can assess which requirements apply.
Can Delwi take care of the surface treatment?
Yes. Within our own coating department, we can blast and powder coat products. This allows the surface treatment to be directly integrated into the overall production process, but you can also engage Delwi exclusively for coating.
What are the maximum dimensions for powder coating?
Our Indufinish powder coating system and Kocken mirror oven are suitable for large steel products.
Maximum product dimensions: 12,000 × 5,000 × 3,200 mm
Maximum product weight: 6,000 kg
As a result, Delwi has the capacity to powder coat very large parts and structures.
What are the maximum dimensions for jets?
With our Rösler continuous blast machine with programmable rail system, we can process products into:
Maximum product dimensions: 12,000 × 2,500 × 3,200 mm
Maximum product weight: 6,000 kg
Can Delwi also wet paint?
No. Delwi has capabilities for powder coating, but does not perform wet painting.
Do you blast or process galvanized or pre-painted parts?
No, we do not accept these parts for blasting or further processing.
Can multiple colors be applied to one product?
Yes, that is possible. The possibilities depend on the product, the construction, and the desired color distribution. Please include the desired color scheme in your request.
What are the maximum dimensions for laser cutting?
Our LVD Phoenix FL 4020 laser cutter features a 6 kW laser source and processes sheets into:
Maximum sheet dimensions: 4,000 × 2,000 mm
Maximum plate thickness: 20 mm
The laser cutter is coupled to a Remmert Basic Tower 4020 automatic sheet metal magazine, allowing serial production to be set up efficiently as well.
What dimensions can Delwi saw?
This depends on the sawing machine used. Our maximum sawing capacities are:
Behringer HBP 313A: 500 × 300 mm / Ø 300 mm
Behringer VMS350: 240 × 120 mm / Ø 120 mm
Bauer VG550 ZA2: 600 × 500 mm / Ø 500 mm
In addition, Delwi is certified for the re-marking of materials according to NEN-EN 10204.
What are the maximum dimensions for CNC milling?
Our largest CNC milling machine, the Mazak VTC 820/30, has a working range of X: 3,000 mm, Y: 820 mm, and Z: 720 mm. In addition, we have several Mazak CNC milling machines, including a machine with robot loading for efficient and repetitive production.
What are the maximum dimensions for CNC turning?
Our largest CNC lathe, the Mazak Quick Turn Nexus 250 II M, has a longitudinal travel of 1,000 mm and a turning diameter of 250 mm. This machine is also equipped with driven tools. For smaller products, we have additional CNC lathes available, including machines with robot loading and bar feeding.
