Technical plastic molded parts.

Have plastic molded parts manufactured: injection molding and extrusion blow molding

Your technical challenges are our mission. We develop and manufacture custom plastic molded parts. Together with you, we implement particularly complex and innovative solutions—precisely tailored to your requirements. With our in-house development team and toolmaking department, we support you from the initial idea through to a production-ready plastic product. With FRIES, you have a reliable partner by your side.

Depending on your requirements, we manufacture your technical plastic molded parts using injection molding or the extrusion blow molding process. To do so, we rely on engineering plastics, modern machinery, and many years of expertise in product development, planning, manufacturing, optimization, and testing of the market-ready product.

Processes for manufacturing technical plastic molded parts

Extrusion blow molding process (hollow blow molding)

Extrusion blow molding machine

Extrusion blow molding is a plastics processing method for manufacturing hollow bodies from thermoplastic materials. In hollow blow molding, the molten plastics (polyethylene, polypropylene) are pressed through a die via the feed screw, creating a tube-shaped preform (extrusion). This is transferred into the blow mold and, using pressure, is formed to match the mold’s internal contours (blow molding).

Injection moldingprocess

In plastic injection molding, the polymers (plastics) are liquefied using an injection molding machine and injected under pressure into a mold (injection mold tool). As it cools in the mold cavity, the plastic hardens and, after opening, can be removed as a plastic injection-molded part. The injection molding process is suitable for cost-effective production of large quantities, taking into account the tooling costs for the molded part.

Questions & answers about our plastic molded parts

Technical molded parts are custom plastic components that we develop together with our customers to solve specific technical challenges. They replace standard products where certain functions, geometries, or materials are required.

Our plastic molded parts are used in almost all industries: mechanical engineering, the automotive industry, electronics, medical technology, and many other areas.

Custom plastic molded parts provide solutions that are precisely tailored to your application. We support the entire process—from development to the finished component—and solve technical challenges that standard products do not cover.

Thanks to our many years of experience in the interaction between machine, tool, and process, we optimize shape, function, and material for each molded part. This is how we guarantee the highest quality and precision.

For technical molded parts, we primarily use thermoplastics. Polyethylene (PE) and polypropylene (PP) are particularly common. Both materials are especially robust, durable, and ideally suited for injection molding or extrusion blow molding.

Yes. Using the extrusion blow molding process (hollow blow molding), we manufacture large, hollow geometries such as containers, tanks, or housings. This process is particularly suitable for voluminous and stable molded parts.

For precise and complex geometries, we use the injection molding process. This enables us to produce highly detailed shapes with high accuracy.

Injection molding is particularly worthwhile for precise geometries and high volumes. The process delivers consistently high quality because each molded part is produced with repeatable accuracy. At the same time, tooling costs are spread across many parts, making production economical. As a result, injection molding is an efficient and reliable solution, especially for series production.
