Plastic Injection Molding for Prototyping: From Idea to Functional Prototype in 24 Hours

Validate your designs using real thermoplastics with HoliPress — without the cost and lead times of industrial tooling.

Plastic Injection Molding for Prototyping: From Idea to Functional Prototype in 24 Hours

Validate your designs using real thermoplastics with HoliPress — without the cost and lead times of industrial tooling.

Where does compact injection molding fit into your R&D workflow?

HoliPress adapts to your development process, whatever stage your project has reached:

Option 1

Start injection molding at the earliest prototyping stage

Test a part’s geometry or material properties right from the start, without unnecessary intermediate steps.

Option 2

The ideal complement to 3D printing

1. Validate the shape

Start by 3D printing a prototype to check its ergonomics, dimensions and overall geometry.

2. Create the mold

Once the design is validated, 3D print the mold cavity using resin.

We recommend SLA, DLP and PolyJet technologies, all of which we have tested for producing high-quality molds for plastic injection molding.

3. Use the right process and the right material

Inject your parts using the actual thermoplastic intended for your final product.

That’s when you use our HoliPress!

4. Get a fully functional prototype

Produce injection-molded parts representative of the intended production material and process. Use them to validate sealing performance, mechanical strength and pressure resistance.

Test multiple materials in record time and reduce production risks

Switch materials in under 20 minutes: With a fast, thorough machine-cleaning process, you can test different thermoplastics — including ABS, PP, PA, PC and PPS — in a single day. Compare their appearance, shrinkage and mechanical properties before committing to production.

Reduce risks before moving to mass production: By validating both the injection molding process and the intended material on functional prototypes, you can identify design and engineering issues before investing in final production tooling.

Cut outsourcing costs and keep control of your R&D:Avoid long lead times and the high cost of outsourcing every prototype iteration. Bring prototyping in-house and develop your products with greater flexibility, control and confidentiality.
