2-Shot Overmolded PCBA (Bottom)
Cavist created the 2-Shot Overmold for electronics that require additional chemical resistance, along with superior abrasion and wear capability. This demo USB overmold shows the most basic approach. The premold safely encapsulates the PCBA with hot melt, while the second shot of TPE is strong, durable and easily color compounded. This bottom view demonstrates a […]

Overmold for Wearable LEO Electronics
A leading manufacturer of wearable law enforcement equipment partnered with Cavist to create a 2-Shot Overmold solution for a point-of-view camera system for Law Enforcement Officers (LEO). The design challenges were immense, but Cavist was able to come up with a solution to move the product from prototyping and into high-volume production.
Custom Overmolded Eyewear PCBA
One of the world’s largest manufacturers of eyewear approached Cavist to manufacture frames for eyewear with embedded electronics and biometric sensors. The application required water ingress protection for the PCBA, along with shock and impact resistance.
Overmolded Cable Jacket
Low pressure molding can be used for strain relief, molded grommets and other features that assist with overall wire and cable management. The adhesives offer excellent flexibility for strain relief.
Overmolded Stacked PCBA and Display
A fully encapsulated PCB, with sensitive SMT components, requires a unique molding approach. This stacked PCB assembly required two molding steps to safely overmold the display and the electronics. Minimizing trapped air and vacuum voids is an important consideration.
Custom Automotive Cable Assembly
A manufacturer of electronic vehicles approached Cavist to help create a charging receptacle for a high volume automotive application. The molding process does much more than provide a robust, well-sealed package. Mounting features are created with insert-molded compression limiters.
Sealed 90 degree Connector
This design allows the cable to exit 90 degrees away from the connector axis. This yields a low profile design that offers plenty of strain relief and good adhesion.
Custom DB Connector
We have a solution for almost all types of connectors. This assembly has sealed DB style connector with a pig-tail of wires that exit the overmold. The overmold also provides access for the two fasteners on either side
Overmolded Large PCBA
This overmolded circuit board stands about 11 inches from end to end and is an important part of a pedestrian traffic control system. It must survive outdoors with 100% reliability. This was a challenging part to mold, but the solution passed all testing.
