Heater & Sensor Encapsulation

Another leading edge technology is a process used to encapsulate in silicone or other elastomers a variety of metal inserts, electronic sensors and low voltage heating elements.

With appropriate material selection and “outside the box thinking” when recommending a new tooling design, C & M Rubber Co. has been tagged by one customer as, “The company to go to when you’re looking for the impossible.” C & M Rubber Co. will collaborate with your organization on the most challenging and your simplest projects to produce a high quality and cost effective rubber part.

Determining Factors: Part Size & Target Piece Price
Insert Composition
  • Insert must withstand clamping pressure during molding process
  • Metal or other thermo-resistant material (400°F)
  • Thermo-resistant ribbon or cord heater assemblies
Encapsulation Method
Physical encapsulation and/or heat activated adhesive bonding which takes place during the vulcanization (molding) process.
Insertion Method
In instances where delicate sensors, heaters or other detection devices will not tolerate the vulcanization process, a rubber part can be custom molded to accept the insertion of such devices in a separate assembly process at our facility or yours.
Elastomer Selection
Silicone is a versatile elastomer that is frequently used in applications requiring UL, NSF or FDA 21CFR177.2600 certification where food contact is common. Other materials such as flourosilicone, urethane, neoprene, millathane, EPDM and natural rubber also are used.
Durometer & Color
Durometer and color can be customized to meet your specification. Durometer can range from 10-90 Duro Shore A. (±5 points) Silicone can be color matched whereas flourosilicone, urethane, EPDM and natural rubber are typically available in primary colors.

Shrink Factor
Variables such as part size, thickness, length, specific application environment, mold type and elastomer used will influence final shrink percentage used. Consult with our engineers for a recommendation.
