In industries such as automotive, household appliances, industrial packaging, technical furniture, or industrial equipment, the manufacturing of custom plastic parts requires reliable, flexible, and cost-effective processes.
Industrial thermoforming has established itself as one of the most efficient technologies for producing high-precision technical and aesthetic components, especially for large-sized parts.
At Plasnor, specialists in plastic extrusion and thermoforming, we support our clients throughout the entire production process: from initial design and material selection to mold manufacturing and the finished part ready for assembly or installation.
What is thermoforming?
Thermoforming is a plastic transformation process in which an extruded sheet is heated until it reaches its optimal malleability point and is then shaped to a mold using vacuum pressure.
This process enables the manufacturing of lightweight, precise parts with excellent surface finish, and is cost-effective compared to other processes such as injection molding.
It is particularly suitable for producing large-format plastic parts with complex geometries, without the need for expensive injection molds.
Thermoforming process at Plasnor
At Plasnor, thermoforming is part of an integrated industrial process, designed to ensure quality, repeatability, and customization in every project.
Design and technical consulting
The process starts with the plastic part design and definition of technical requirements: geometry, tolerances, thickness, surface finishes, and usage environment.
Our technical team provides guidance from the early stages in selecting the most suitable plastic material, such as ABS, HIPS, PMMA, PET, PP, or PC—some of which are extruded in-house.
Thermoforming mold manufacturing
Once the design is validated, the thermoforming mold is developed—crucial to ensuring dimensional accuracy, process stability, and production repeatability.
In-house plastic sheet extrusion
Plasnor has its own plastic sheet extrusion capabilities, allowing for customized colors and textures, high dimensional stability, and consistent quality across batches.
Heating and vacuum forming
The extruded sheet is precisely heated and shaped to the mold using vacuum pressure, ensuring fine detail definition, complex geometries, and excellent surface finish.
Cooling, finishing, and quality control
After forming, the part is cooled, demolded, and undergoes trimming, machining, and quality control before being prepared for logistics or assembly.
Large-format part manufacturing capabilities
Plasnor can produce thermoformed parts up to 3 × 2 × 0.9 meters, such as technical covers, plastic panels, industrial trays, and large-sized components.
