Cryogenic Shrink Fitting for Tight Tolerance Parts

Shrink fitting uses temperature to change the dimensions of parts so that components fit and hold together. This joining technique is used in sub-assemblies to create a tight, interference fit between inner and outer components so that relative motion won’t occur or force can be transmitted from one part to another. Common shrink fitting applications […]

Dry Ice Cleaning for Injection Molds

Injection molds that are cleaned with dry ice blasting are helping plastic and rubber molders to reduce costs and improve quality. Dry ice cleaning removes surface residues without creating secondary waste. It also eliminates time-consuming scrubbing and won’t harm mold surfaces. Importantly, dry ice blasting allows operators to clean molds that are hot and still […]

Cryogenic Treatment for Vacuum Tubes

Vacuum tubes that are cryogenically treated can improve sound quality in music and audio applications. Cryogenic treatment, a process that modifies the micro-structure of metals by subjecting them to ultra-cold temperatures as -300° F, is commonly used to increase the durability and wear resistance of steels but can also maximize the sonic performance of electrical […]

Cryogenic Deflashing for Medical Silicone Parts

Medical silicones can be molded into parts such as distal handles for surgical instruments and dental tools. There are many types of silicone rubber, but medical grade silicones need to meet biocompatibility requirements such as USP Class VI or ISO 10993. Then, after they are molded, medical silicone parts need to have a finish that’s […]
