Prototype Silicone Molding
Albright’s concentration is on the rapid prototyping of molded medical silicone parts, but is also highly experienced with the prototyping and manufacturing of micro molded silicone rubber parts for medical, military, government, industrial and consumer applications. Albright is ISO 13485 certified and has a Class 7 clean room, on site.
Silicone is the choice material for medical applications due to its biocompatibility, but has additionally desirable properties such as: high compression set, chemical resistance and high fatigue resistance. These properties are not typically found in thermoplastics elastomers.
Silicone Molding Methods
Liquid Silicone Rubber (LSR) is typically injection molded and High Consistency Rubber (HCR) is frequently transfer molded but both materials lend themselves well to compression molding. Medical grade silicone products are available in both LSR and HCR forms.
Compression molding is ideal for the rapid prototyping of molded silicone parts. Compression molding can quickly complete short runs of prototype parts for proof of concept, concept validation, functionality testing and clinical trials. A single cavity hand operated compression tool can be a fast and economical way to learn critical details in part processing and iron out any design problems prior to designing a large multi-cavity liquid silicone injection production mold.
How it Works
Albright Technologies typically starts with a simple, single cavity compression tool, for both LSR and HCR materials, before designing multi-cavity LIM (Liquid Injection Molding) or automated transfer molding tools. This allows short run prototype silicone parts to be shipped to the customer in as little as 5 business days.
Medical device designers face many choices when selecting a silicone material, designing a tool and medical silicone part prototyping for clinical trials. Albright Technologies will work provide the customer with manufacturing advice and work with the designer to select the best process for them.
