Injection Molding Machine Housing: manufacturing notes
Injection Molding Machine Housing has to survive its application, not just its inspection report. This page sets out how the part is actually made — the material decision, the forming sequence and the tolerance strategy — so a buyer or engineer can judge whether the specification matches the application before a drawing is even sent.
Why this part is made in cold-rolled steel
Injection Molding Machine Housing is specified in SPCC steel 2.0mm. Cold-rolled mild steel is the most predictable substrate in the shop: consistent thickness, tight bend behaviour and a surface that takes powder coat evenly. It has no inherent corrosion protection, so it is normally paired with a coating system, and any cut edge stays protected only as long as that coating is intact.
How the part is formed
The production route for this part is Laser Cutting, CNC Bending, MIG Welding. Fiber laser cutting separates the blank without hard tooling, which is what makes a first article economical: the profile can change between the prototype and the production run without a die sunk. The trade-off is a small heat-affected edge, so on parts that will be painted we deburr and, where the edge is a sealing face, dress it flat before coating. Bending is where most tolerance stack enters a sheet metal part. We set the bend allowance from the part’s own material and radius using the K-factor the press is running, then verify the first article on the machine rather than from the drawing, because springback moves with material batch and grain direction.
What ± 0.1 mm actually requires on the shop floor
The drawing calls for ± 0.1 mm. On a part like this that is a process decision, not an inspection decision: it fixes which machine holds the critical features, how the part is fixtured for each operation, and whether a formed feature can be checked after coating or has to be measured before it. We confirm the first article against the drawing and record the values, so the tolerance is demonstrated rather than assumed. If a dimension in your drawing is tighter than this part needs, it is usually worth relaxing it — over-toleranced features are one of the quietest cost drivers in a sheet metal quote.
Finishing: powder coating
Powder coat RAL 7035. Powder coating builds a film of roughly 60–120 µm per face and cures at 180–200 °C. Two consequences get designed for: the film adds to every mating dimension, and the cure temperature is high enough to move an unsupported panel, so stiffening or return flanges go in before the part reaches the oven. Colour is matched to the RAL range given on the drawing.
Frequently asked questions
- What is the minimum order quantity for injection molding machine housing?
- The order range for this part is From 1 to 500+ volume. Below the low end of that range the tooling and setup are spread over too few pieces to be economic, so if you are prototyping we would normally build the first units from the same process route and quote the production quantity separately.
- Can the material be changed to reduce cost or weight?
- Yes, and it is worth asking before the design is frozen. The current specification for this part is SPCC steel 2.0mm; depending on the service environment, a different grade or a lighter gauge with formed stiffening can meet the same requirement. What we would not do is change the material without re-checking the bend radii, the welding process and the coating system, because all three move with the substrate.
- What finishing options are available for this part?
- The current finish specification is Powder coat RAL 7035. Powder coating, anodising, zinc or nickel plating, brushing and blasting are all available in-house, so the finish can be changed without changing supplier — and where the part will be seen, we match colour to the RAL or Pantone reference on your drawing.
- How long does production take, and what do you need from us to quote?
- Prototypes are typically 3–7 business days and production runs 7–15 days once the drawing is released and the finish is confirmed. To quote we need the drawing or CAD file (STEP, DXF, DWG, IGES or PDF), the material and finish, the quantity and the destination — and any tolerance or inspection requirement that is not already on the drawing. You get a DFM review with the quotation, not after it.
