The plastic covers, which we manufacture individually for you, are sturdy, durable, flexible, and hygienically resistant if needed. They effectively protect your machine or device and thereby increase the lifespan of your product. Thanks to our modern manufacturing methods in thermoforming and CNC machining, each cover element can be precisely and cost-effectively adapted to your requirements.

Customised filters and screens with plastic mesh

Plastic housings are ideal for applications where functionality, light weight, durability, and aesthetics are crucial. With a thoughtfully designed plastic housing over the individual components, the end product operates reliably and lasts a long time.

Production at LEGROM is almost exclusively fully automated. To ensure optimum injection molding conditions, the granulated material is pre-dried in a central drying system and then fed from there to individual machines via a pipe system. Our state-of-the-art machinery and spotless machine environment meet all the prerequisites needed to assure the level of quality and flexibility demanded. Consulting in plastics technology Global delivery capability Injection molding machines with closing forces ranging from 350 to 2000 KN Injection moldings ranging from 0.01 to 400 grams in weight Single and multi-component injection molding Insert molding (metal and ceramic) Depositing of components through handling systems or robots High-performance thermoplastics at LEGROM Practically every high-performance plastic available on the market is used at LEGROM, ranging from PA, PBT, POM or ABS to PMMA, PPO, PPA, PAA and PES, PSU or PEI engineering plastics to high-performance thermoplastics such as LCP, PPS or PEEK. LEGROM has the appropriate solution for every plastic, both in mold construction and injection molding production. LEGROM also processes all conventional fillers, including glass fibers, carbon fibers, glass spheres, PTFE, carbon or titanium dioxide. Special mold materials and special machine equipment is available for every filler. LEGROM can realise up to 70% filler content of the raw material.

Ultrasonic welding technology for demanding applications with high quality requirements The Federal Institute for Drugs and Medical Devices defines medical devices as products with a medical purpose that are intended by the manufacturer for use in humans. Medical devices include, for example, infusion accessories such as drop sensors. A special seam design in conjunction with a contour sonotrode enables a watertight weld here. In this product, the lid is welded with a finely grained surface without damaging the visible side. Ultrasonic technology offers versatile solutions for applications in the medical sector. The use of ultrasonic is also an established process for the classic production of face masks, as well as for the manufacture of FFP masks and hygiene and protective equipment. These applications can be found here: Industries » Technical Textiles » Nonwoven.

Plastic parts

The crushed granules are then fed into the injection molding machine and heated. They are then injected into the molds at the right temperature and time.

In mechanical and plant engineering, we offer customized plastic solutions for a wide range of industries – from manufacturing and technology to energy and medical technology. Our production capabilities include prototypes, pre-series production, and large-scale production using 3D printing and injection molding. This allows us to respond flexibly to individual requirements and deliver precisely fitting components. Our LTK® products made from Lauramid are characterized by their versatility: Lauramid® technical plastic, our special PA12C, is the ideal material for mechanical and plant engineering. The material is processed using injection molding and then precisely machined according to your specifications. This results in high-quality components that are optimally tailored to your technical requirements. Thanks to our e-coating (KTL) production, we support you from the initial concept to the finished product. From model making and 3D printing to injection molding, we manufacture a broad product range – from A for covers to Z for gears. Rely on our expertise and flexibility in mechanical and plant engineering.
