Molds and Jigs dedicated to the aerospace industry

For over 20 years, Pinette PEI. has used its expertise in molds and assembly systems to serve the largest groups in the aerospace industry. We provide custom engineered molds and jigs for rockets & satellites applications.

Assembly, milling and control of composites sandwich casings for ARIANE 5 rocket

Our assembly, milling and control mean illustrates Pinette PEI's know-how and performs: 

• Drilling
• Assembly
• Milling in interpolation
• Automated dimensional control

Application: large composite sandwich casings used for satellites carrying on ARIANE 5.

• Optimised design : high comfort of use for operators
• Capacity of Ø 6,000 mm
• Driven by 6 axes CNC.
• References precision of +/- 0.2 mm
• Displacement precision < +/- 0.1 mm

Molds for composite materials

Pinette PEI. is a well-known supplier of molding workstations and molds for composites materials:

• Tubes
• Structural parts
• Large size parts

Our molds in welded steel have a very high rigidity, which permits to secure the parts geometry and to ensure a high precision. All the molds are designed to be operator friendly and show a high reliability, after 15 years of production for the oldest ones.

Molding workstations can process composite parts with length up to 6,500 mm, width of up to 3,500 mm and diameter up to 4,000 mm in order to fulfill each of our customers' needs.

Molds for satellite solar panels

Pinette PEI supplies molds for satellite solar panels, made of welded INVAR steel. The adjustable geometry of this range of mold compensates the deformation of the parts after curing, even for parts with length up to 4,500 mm and width up to 3,500 mm. Our products also guarantee geometry of the molded parts with an excellent flatness and high repeatability.

Assembly jigs for composite parts

Our technical teams have worked hard to present you a complete range of assembly frames, with a confirmed reliability thanks to more than 10 years of service in continuous production.

Applications:

• Light alloy lattices structures
• Internal components of cryogenic tanks
• Cylindrical structure of civilian launchers

Features:

• Capacity of Ø 5,600 mm
• Interfaces precision lower than 0.1 mm
• Classification 100 for all materials and surface treatments

Cutting unit for ARIANE 5 cryogenic tanks insulating panels

Along assembly means, Pinette PEI. provides cutting unit of insulating panels for cryogenic tanks of the ARIANE 5 launcher.

Features:

• Work on panels up to 2,500 x 2,500 mm dimension and a spherical radius of 3,000 mm
• 3 axes CNC
• Precision of +/- 0.2 mm.

This production mean needs only low maintenance, as it has been used for more than 15 years without intervention except preventive maintenance.
