From design to the final piece

Based on your requirements, whether it is custom parts or parts from the catalog, Piercan offers you the best solution via a controlled process - design, manufacturing, inspection. Quality has always been the focus of all our attention.


Design Office 
Analyzes your requests and assists you in finding the most suitable solution. The design office also plays a role in developing new products in three stages: 
- Choice of material: nature, color, transparency and physicochemical properties. 
-Product development: draw the shape according to the shaping technique.
- Prototyping: form taking and dimensioning, creation of drawings, cutting of templates, development of tools, realization.

Economic optimization
The study of solutions adapted to your needs integrates quality factors, delays and production costs, thus facilitating the economic optimization of your project.

The cut 
For cutting, we use circular blades and vibrating blade scissors. Semi-automatic end cutting:
- Cutting in mattress format
- Cut to size
- Unit cut to the shape

The welding 
- Manufacture by high frequency welding (chemical bonding of the materials by molecular stirring created by a high frequency field). - Technology that guarantees perfect sealing of the assemblies. 
- Powerful, extensive welder pool suitable for containment items. 
- Wide range of electrodes.

- Compatible with cleaning, decontamination and disinfection agents.
- Glove box and insulator handling welds: strong, flexible, smooth and resilient.


We guarantee the quality of our products by supervising every stage of the manufacturing process:

1 • Prior inspection of the raw materials and tools along with a check of the custom dimensions using our production management software.

2 • Inspection of the physicochemical parameters by the quality control laboratory and the production parameters by the operators during production.

3 • Inspection of the finished product
