YUSA’s rubber prototyping molds.

Prototype Molds

Locally sourced tooling allows YUSA R&D more control and improved communication with suppliers and customers. Tooling includes making the individual components, replaceable mold cavities, the rubber molds themselves, dies for post-processing, and fixtures for testing and dimensional verification.

YUSA’s prototype rubber molding press heats up the rubber in the mold for optimal hardness.

Prototype Rubber Molding Press

In order to obtain the highest quality parts most efficiently, the vulcanization parameters should be controlled precisely. YUSA R&D has the expertise in setting and maintaining those parameters to be used in prototype and into production. Variables such as injection speed, temperatures, cure time, etc are all part of the initial tuning of parts in order to achieve and sustain the customer’s requirements.

YUSA simulation output and CAD data analysis.

CAE

A critical part of the development process involves performance prediction techniques utilizing YUSA R&D’s FEA simulation tools. YUSA engineers regularly evaluate 3D models using tools including CATIA, ABAQUS, and Endurica in order to output useful information such as theoretical stress and strain, fatigue analysis, and static characteristic predictions.
