Everybody wants to save money and efforts on manufactured parts. It looks easy, but one of the simplest ways to reduce cost-per-piece in injection molding is through rising part quantity. That is due to the reason that the initial upfront price to design as well as machine the mould amortizes over many parts.
Below are 11 injection molding design suggestions to reduce your manufacturing cost when getting Plastic Moulding Services:
1. Eliminate undercuts
2. Use a core cavity approach
3. Get rid of unnecessary features
4. Reduce cosmetic finishes and appearances
5. Design self-mating parts
6. Pay attention to DFM analysis
7. Modify and reuse molds
8. Use a multi-cavity or family mold
9. Consider part size
10. Choose on-demand production option
11. Use overmolding
Undercut features set hurdles and, in several cases, avoid part ejection. Dispose of them if you can, but maybe this is not feasible, if, for instance, you require a side action, sliding pick out or shutoff. One option may be utilizing sliding shutoffs as well as pass-through cores, or through changing the parting line & draft angles to grant a simpler mold build. These lessen tooling costs since you avoid supplementary pieces to the mold which add to manufacturing price. Apart from the rise in manufacturing price of utilizing hand-loaded inserts, this additionally may have an influence on your piece part price due to longer cycle times as well as manual mold operation.
If you require an electronics housing or analogous box-shaped part, you could either sink the fence cavities deep under the mold base, needing long thin tools to machine the aluminum material down around the core or ribs into the mold and mold the part around it. The latter method is known as a core cavity, which is a far more cost-effective approach of molding tall walls as well as ribbed surfaces. Better yet, it makes it simpler to grant smooth surface finishes, improved ejection, adequate venting, and can eradicate the requirement for super-steep draft angles.
Considering a core cavity can be a cost-effective approach of molding tall walls as well as ribbed surfaces.
Perhaps you’re making a snap-together case for several medical components, or else 2 interlocking halves of a handy radio. Why design two mating parts if you are capable to make one? Redesign the snaps in order that the halves could be fit together from all direction, hence building a supposed “universal” part. Just one mold is required, saving production expenses straight. Ultimately you can now mold two times as many of one part, rather than half the quantities of 2.
