About Us





Kingson Mold and Machine is a global leader in liquid silicone rubber mold making, offering manufacturing solutions for the medical, aerospace, automotive, electronic and consumer industries.

The company was established in 1977 by Jack and Greg Rex, a father and son team, in Brea, California. Since then we have been dedicated to providing the finest quality molds and tooling systems to rubber and plastic processors, on-spec and on-time.
Our mission is to partner with our customers, bringing ideas and tooling solutions that add value to their organization and profit to their bottom line.
Kingson is experienced in building molds for a wide variety of polymers, including organic rubbers, silicone rubbers and thermoplastic materials. Molds range from simple compression and transfer tooling to complete injection systems with fully automated parts removal.
We also offer a choice of integrated services, ranging from help with part design to complete tooling design, prototype tooling, production tooling and pre-production tool prove-out. If required, we also offer interim or ramp-up production of parts from new liquid silicone (LSR) or LIM tooling. In short, we can take your project from concept to interim production, delivering proven solutions to meet all your productivity needs.
