Rubber crosslinking is a chemical transformation that results in an irreversible reaction. This process, carried out by sustained heating during vulcanization, removes the rubber’s plasticity and imparts new mechanical and chemical properties. The first stage in rubber molding involves preparing a compound that meets both technical requirements and customer specifications.

Based on a set of specifications, BH TECH fully manages the design and manufacturing of elastomer molding tools. Elastomer molding can be performed with or without inserts, and applies to parts ranging from a few grams to over one hundred kilograms.
Rubber molding can be carried out using three main techniques: compression molding, transfer molding, and injection molding.

BH TECH has developed strong expertise in the molding of rubber-metal assemblies. This technique is widely used in applications requiring sealing or vibration damping.
By combining the mechanical strength of a rigid metal structure with the flexibility of rubber, this process produces assemblies with significantly improved performance over conventional mechanical assemblies.
Rubber-metal bonding requires precise surface preparation of metal inserts, including the application of bonding agents that enable chemical adhesion between the metal and the selected elastomer.

Bonding is a surface preparation technique used to chemically attach a soft elastomer or rubber to a rigid material. This process relies on a chemical agent and is activated by temperature and pressure. It is suitable for bonding rubber to metals, plastics, fibers, and resins.
