Hi everyone,

Looking for tips on the reduction of injection mould tooling cost, and part cost. I've listed my current methods below, however my main curiosity is:

>>>>>>>>>>>>>>>
If I've 4 small parts, for example, is it cheaper to join in CAD into one part, and mould as one part? (please ignore post production automatic cutting process costs).
>>>>>>>>>>>>>>>

Current methods of reducing injection mould and part cost:

- Focus on symmetrical part design (moulding 1 part in double quantities)
- Harmonize part depths, to match, on 1 mould tool blank
- Multi functional parts
- Use mould keys, for selective injection of parts, saving on multiple mould tools

>>>>>>>>>>>>>>>>>>>
Also interested in lists/resources to other cost reduction methods, for part and mould cost
>>>>>>>>>>>>>>>>>>>

thanks / simon

 

Hi!
While considering cost & material details, reducing the no. of mold will achieve the low cost in overall production. For example; while your design contains two different parts with same material & weight, try to allocate them in a single family mold. so that you may reduce the no. of mold on whole design.

Re-consider/re-check your product design, regarding appearance level; to modify gates & side core concepts to minimum level & simple concepts.

Re-consider/re-check your production requirement to finalize no. of cavities in all molds.

Try to get mold bolster as standard one.

Thanks.
