Our OMOM® approach allows us to eliminate unnecessary communication and queue time, but also allows us to create very complex tooling quickly. Time is money.
New designs commonly require tool modifications. At STAR we already factor in a number of design revision related tool modifications. Happy to help.
Although our OMOM tooling is for prototype and low-volume runs, we aim to give you production quality finishes. If you design to industry standards, we can do it.
We are able to combine the cost savings of Asia with the expertise of our international team of managers and engineers to provide best-in-class performance at a competitive price.
Plastic Injection Molding
Our prototype injection molding process allows us to create molds for simple to complex parts, in short lead times and with attractive costs. Prototype injection molded parts are ideal for one-off to hundreds of parts. For most prototype injection molded parts, Star Prototype uses pre-hardened P20 tool steel or 7075 aluminum to make the core, cavity, and ejector plates, then inserts these into a Master Unit Die (MUD) base.
50 to 1000+ Injection Molded Parts
For Prototype Molds we typically use pre-hardened P20 tool steel or 7075 aluminum to make a complete stand-alone mold. We can add custom cooling circuits, hot tips, and other refinements to aid with the production of technical resins or complex geometries. For polished or high-gloss parts, we use NAK-80, a polishing stainless steel.
Very low volume production of injection molded parts is ideal for a few hundreds up to thousands of parts of varying complexity. This process offers medium tooling and part price.

1000 to 100,000+ Injection Molded Parts
For Pilot Production molds we typically use pre-toughened, high-quality P20 tool steel or NAK-80 stainless tool steel to make a complete mold, which is, in effect, a full production tool without full hardness. To reduce lead times and costs, we do not offer these molds for export; all of our Pilot Production, or ‘Bridge tooling’ molds are built to local standards. Low volume production injection molded parts are ideal for thousands to hundreds-of-thousands of parts of varying complexity. This process incurs a higher tooling cost, but a much lower part cost.
100,000+ Injection Molded Parts
These are full production injection mold tools that will be exported outside China for our customers to run in their own facilities or at a local molders (only available for export to USA currently). Molds are to full USA / western standards. Typically up to 8 cavity molds, maximum injection mold press size 500 tons, steel type P20, H13, NAK 80. Open and shut, multi slide, unscrewing etc. are all available. If you have a requirement for full production molds where the molds will be exported to you, contact our export mold team firstname.lastname@example.org

Unless otherwise specified, we comply with the DIN 16742 standard tolerances for plastic injection moldings. We need to know your requirements in advance so that we can manage key features in the tooling and molding process. As a general rule, you should never make more than one feature very accurate in the design. That feature can be repeated across the part, but to make a whole series of very different features very accurate is impossible for any molding company to achieve – you end up chasing your intolerances around the part. You get one feature right only to find another one slightly off. A general guideline for tolerances can be downloaded here: Star Prototype: Plastic Injection Molding Tolerance Guide
Plastic Injection Molding and the Challenge of Color Consistency”: Color consistency for injection molded parts poses a challenge. This becomes apparent for mating parts in any assembly where colors usually need to match 100%. Some production batches may require stringent … “Star Prototype – read more“
