Heat sealing is the process of sealing one thermoplastic to a similar thermoplastic using heat and pressure.

Schwerdtle makes different products that are ideal for heat sealing applications. Our high-temperature, conductive silicone bonded to metal can be made into flat sheets, rollers or bars, or molded into complex shaped dies. These tools are heated and kept at a constant temperature (also known as Direct Contact Thermal Sealing).

Silicone Seal Heads

Silicone Seal Heads offer complete coverage of surface imperfections ensuring consistent, reliable seals leading to higher yields and reduced scrap.

Silicone Coated Seal Jaws provide an effective solution for sealing package inconsistencies caused by food contamination, thick or multiple layers of film, product dust or particulate.

Anodized backings: All aluminum substrates (that the silicone is bonded to) can be clear anodized or hardcoat anodized to seal the metal surface where contamination-free operations are required. The anodizing process does not affect the silicone face or properties. Anodized backings are often used in food, medical and electronics packaging operations, and is commonly specified for tooling used in clean rooms.

Schwerdtle prides itself on providing precision, quality products to our customers. How can we help you? Give us a call to discuss your needs today!
