Da/Pro Rubber manufactures custom products including diaphragms, seals, connectors, custom shapes, rubber-to-metal parts and more. Its facilities are located in Oklahoma, California, Massachusetts, Singapore, as well as Malaysia, and it has ISO 9001-certified facilities and a class 10,000 cleanroom. Known for high-precision, close- tolerance moulding services, Da/ Pro Rubber can manufacture LIM/LSR products to these same demanding standards. The compression and transfer moulding consists of proprietary processes developed by Da/Pro Rubber. The presses are designed to adjust for compound or part- configuration variables. The moulding process is computer- controlled and monitored to maintain consistent moulding conditions, assuring the duplication of the product throughout the moulding cycles. When it comes to material development and qualification, Da/Pro staff chemists are available to develop organic, inorganic or silicone compounds to satisfy specific customer
is monitored throughout each process, using a system based on ISO 9001 standards, an advanced statistical process control is used to monitor material properties and mixing, moulding operations and final product conformance
to specification. The final proof of the success of these efforts is the part itself. To ensure quality, all parts are visually inspected to check that they conform to design criteria. In addition, leak and deflection testing for diaphragms and insulation testing for connector inserts may be specified. Whatever the customer’s moulding needs, Da/Pro has the expertise, experience and world-class service necessary to find a solution.

Parylene C coating for NdFeB magnets
Parylene C, which provides superior performance. Parylene C is a transparent, pin-hole free, conformal coating that coats thinly, and has ideal barrier and corrosion resistant properties required for medical applications. Dexter began developing its in-house BarrierMax coating process in 2018 and tailored its formulation to optimise performance on NdFeB magnets. Process variables were systematically tested and adjusted through a series of rigorous accelerated life and adhesion tests, which included: ■ cut and lift testing ■ salt spray per ASTM B117 ■ elevated temperature saline bath submersion ■ highly accelerated
temperature and humidity stress test (HAST).
The coating process is comprised of three stages: sublimation, pyrolysis and deposition. The coating process begins with raw material (dimer) being heated under vacuum and vaporising at approximately 150°C into a dimeric gas.
The dimeric gas is then
Dexter produces high-quality Parylene C coating for implant applications.
Biocompatible coatings are critical in the medical device world, especially in implantable applications. Dexter Magnetic Technologies has developed its own process for coating NdFeB magnets with BarrierMax
pyrolised (thermally decomposed at an elevated temperature in an inert atmosphere) at a temperature of 650°C to a monomer gas. The dimeric gas is then pyrolised (thermally decomposed at an elevated temperature in an inert atmosphere) at a temperature of 650°C to a monomer gas. Then, finally, in the room temperature deposition chamber, the monomer gas deposits under vacuum of about 0.1 Torr on all surfaces as a thin, transparent polymer film.
Dexter continues to advance its technology and leverage customer needs based on the end user’s requirements. Whatever the need, Dexter can produce the highest
