Kusla has years of experience in prototype injection molding and tooling services. We save our customers both time and money by using aluminum or softer steels like P20 for the toolings. This choice not only reduces overall tooling costs but also significantly decreases the lead time.
Our prototype injection molding services are non-limiting. you can not only get one prototype with production grade material and also low volume injection moding parts according to your specific project requirements.
Custom Molded Prototypes and Production Parts with Fast Lead Times
injection molding with high-quality raw materials including all common thermoplastics and some thermosets as well as liquid silicones.
Overmolding uses a multi-step injection molding process to make one component or layer over top of another component or layer.
Insert molding is an injection molding process that involves adding inserts, particularly metal, into an injection molded part.

Aluminum mold tooling is the perfect option for prototype injection molding because it offers a cost-effective way to produce molded parts. aluminum is easy to machine that could shorten cycle times by 30-40%, result in cutting cost saving by up to 25%. Additionally, Aluminum mold tooling provides excellent dimensional stability, which minimizes waste and reduces part deformation during production.
Soft steel mold tooling is another excellent choice for prototype injection molding with a longer life cycle. It is more suitable for low volume production runs and for producing parts wiht high quality surface from engineering-grade plastics. However, it is more expensive than aluminum and may require more time to produce mold tooling and injection molding prototypes.
The best injection molding uses high-quality materials. At KUSLA, we work with various plastics, including all thermoplastics, some thermosets, and liquid silicones.
Polyoxymethylene (POM)
Polybutylene terephthalate (PBT)
Polyvinyl Chloride (PVC)
Polyetherimide (PEI)
Polystyrene (PS）
Thermoplastic Polyurethane (TPU)
Thermoplastic Elastomer (TPE)
KUSLA Prototype follows SPI standard to define the surface finish of injection-molded parts.
Prototype injection molding, also known as rapid injection molding, is a method that uses rapid soft tooling to produce injection-molded parts much faster than traditional tooling methods. This speed is achieved by utilizing aluminum or soft steel tools, simplifying the design, or streamlining the manufacturing process. As a result, these tools are more affordable to produce, making them ideal for the budgets of rapid prototyping project which required production grade materials and low-volume production.
To make prototypes with production grade materials and production quality for product design validation tests.
Prototype Tooling is typically made of cheaper materials, less complex which means less expensive to produce.
the prototype injection molding process allows for quicker turnaround with parts in your hand in as little as 2 weeks.
Start with a small volume run to validate your product before investing for mass production.
Most frequent questions and answers about our prototype injection molding service
Yes, injection molding could absolutely be used for prototyping. Typically, for projects that require production grade materials prototypes and low volume production for validation tests.
A small and simple single-cavity plastic prototype mold usually costs range from $200 to $2000. a large and complex prototype mold may costs over $20000.
Injection molding cost consist of initial cost of tooling and injected part cost. So the more parts injected, the less tooling cost amortize in piece price. Our injection molding cost starts around $500 and will vary depending on part geometry and complexity.
Yes, in some simple case, we can make 3D printing molds for injection.
Not really, prototyping with injection molding enables a much more comprehensive range of materials, finishes, and textures that other processes do not offer. 3D printing can offers shorter lead times, but its cycle times are longer and fewer plastic materials are available.
After receiving the order, we wil create a comprehensive DFM report for your approval. Upon approval, tooling and mold production is commenced. T1 samples will be produced and shipped for approval. Upon approval, the remaining parts are made.
we often provide advanced DFM in the forms of parting line visualization, draft analysis, and mold-flow analysis upon request.
Yes, KUSLA will conduct mold flow analysis as a standard process before building the molds.
