Design for manufacturing: cost is decided at the design stage.
DFM ensures products are cost-effective, easy to produce, and consistently reliable. Correcting issues during the design phase costs very little. Resolving the same issues after tooling is built costs a fortune.
Changes must be found at the beginning of the development cycle.
Changes identified early can have a large effect and cost little. Design flaws found later are hard to implement and expensive.
In injection moulding the mould is a substantial investment, so changes should be settled before mould design and construction start.
What you receive
Final Mold Design with a list of the correcions/modifications agreed with the toolmaker and integrated in the mold desegn.
In depth where we are experts. With your supplier everywhere else.
Injection-moulded parts and assemblies
During DfM for a moulded part we study in detail:
- Mould steel quality
- Opening direction of mould and slides
- Parting line
- Sub-inserts
- Ejector type and position
- Weak spots in the mould
- Filling and cooling
- Gates and runner system
- Number of cavities
- Surface quality
- Dimensional and geometric tolerances
- Warpage, sink marks, weld lines
For assemblies: snap-fits, ultrasonic welding, screws and threaded inserts, and how each joining method affects the part design.
Sheet metal, rubber, die-casting, machining and more
We apply the general design rules of each process and communicate directly with your supplier on the technical details, so the drawing that reaches the shop is one it can make at the right cost.
Materials and demanding applications
Long experience with commodity polymers, engineering thermoplastics (polycarbonate, polyamides, flame-retardant and glass-reinforced polyesters) and extreme materials such as PEEK or PVDF. Advice on electrical safety, outdoor weathering, airtightness and flame retardancy.
