About Compuplast

1991

Compuplast was founded in 1991 and has specialized in the development and manufacturing of extrusion lines and tools for plastics ever since. Using modern CAD software—first AutoCAD and, since 2001, Solid Edge 3D CAD—we design equipment precisely tailored to our customers’ needs.

2018

To support our products and services, in 2018 we opened a new 550 m² office space with a modern showroom and prototyping workshop.

2019

In 2019, we launched a testing extrusion line for 3D printing filaments and small tubes. This enabled us to physically demonstrate the technology we offer to our customers and, most importantly, to successfully give customers the opportunity to test that technology themselves—an option many customers, including international ones, take advantage of.

2022

During 2022, we renovated and completed another workshop, expanding the company’s total area to 680 m². This is a production workshop with machining equipment, allowing us to manufacture a large portion of the technology we offer in-house.

2026

Our latest expansion in 2026 added 120 m² of production space. This expansion allowed us to separate the machining section from material preparation (cutting and welding), improving not only logistics and material flow but also the cleanliness and noise conditions in the machine shop. Thanks to our many years of experience, modern technology, and personal approach, we provide comprehensive solutions for manufacturing extrusion lines for filaments, plastic profiles, and tubing.
