Prototyping

Manual plastic injection prototyping

Manufacture of valve parts

This case study presents the use of manual plastic injection prototyping with HoliPress for the manufacture of prototypes of valve parts. Our client, a valve specialist, was looking to produce prototypes using plastic injection because 3D printing and plastic machining did not guarantee the necessary resistance to pressure tests.

Step 1

Design of 3D models

The engineering team used Computer Aided Design (CAD) software to create 3D models of the valve parts to be prototyped.

Step 2

3D printing of molds

3D resin molds were printed to match the 3D models of the parts. These molds will be used to contain the plastic during the injection process.

Step 3

Plastic injection

The engineering team used HoliPress to inject the desired industrial material, in this case POM (polyoxymethylene), into the molds. This step resulted in the production of pressure-resistant plastic prototypes.

Testimony

Thanks to plastic injection prototyping in good material, the injected parts were able to withstand a pressure of 25 bars, unlike prototyping carried out by machining.

The added value of our solution

Speed of implementation

Prototypes produced quickly, thus accelerating the development cycle.

Reduced costs

A method that has proven to be economical compared to other prototyping alternatives.

Good material

The prototypes were resistant to pressure tests, which was essential for the company.
