Production Capabilities

One Integrated Development & Production System

JOINSET is more than a component supplier. Product engineering, application engineering, material processing, in-house tooling, manufacturing, and testing work together within one integrated in-house system from initial design through prototype, qualification, and mass production.

Customer drawings and performance targets come first

Many design challenges cannot be solved with an off-the-shelf part. JOINSET engineers work directly from customer drawings, performance targets and application conditions. This shortens development cycles and de-risks the transition from prototype to volume production.

In-House Manufacturing Capabilities

Tool and mold fabrication

Plating

Etching

Material mixing and formulation

Casting

Extrusion

Foaming

Press

Assembly & Packaging

In-house manufacturing allows engineering and quality teams to control critical processes closely and respond quickly to customer requirements.

Quality & Reliability

Reliability is engineered into every product

For JOINSET, reliability is a fundamental design and manufacturing requirement. Material selection and product design are connected to manufacturing, inspection, testing, and mass production so components can perform consistently throughout the product lifecycle.

Our quality management is verified under international standards and customer-specific audits, from ISO systems to VDA 6.3.
