LSR Molding: High or Low Viscosity?
The first example of silicone rubber was produced as early as 1872. The substance was very viscous oil, developed by reacting diethoxydiethysilane with water and trace amounts of acids. The first commercial grades were produced in 1943, only high-consistency rubbers (HCRs), by the Dow Chemical Company, with many other companies following shortly after. It was not until the late1970's that a "pumpable" silicone rubber was developed and available to fabricators. Since then, LSR's have continued to evolve and have surpassed use of HCRs for injection molding. Liquid Silicone Rubber has come a long way and today, is utilized by a variety of industries, from automotive to medical.
Comparative Analysis of SLA Resins
Rapid prototyping service bureaus are often the first to hear the new marketing claims of the resin suppliers, all claiming to offer the latest and greatest resins. They all sound great at the onset, but many resins don't quite live up to the marketing claims. At the same time, you as a customer count on rapid prototyping service bureaus to be experts at Stereolithography, and frequently ask your rapid prototyping provider to make SLA resin recommendations for your applications.
And so it's of vital importance that a real-life, objective test be developed. A test used to learn about the relative performances of the resins, so recommendations based on personal experience, rather than the hearsay of a resin salesman, or numbers on a spec sheet. Following are the results of the test we developed.
Why Choose RTV Molding?
We use the process of silicone RTV (Room Temperature Vulcanization) molding to create beautiful, accurate, and functional cast urethane parts from your CAD files. This is a great alternative to multiple rapid prototypes, giving you better looking and more durable multiple parts and assemblies.
