A LOW COST METHOD FOR MAKING SMALL NUMBER OF PLASTIC PROTOTYPES
WayKen Vacuum Casting technology offers a wide variety of urethane casting material for engineering testing, proof-of-concept and display demos parts, typically for pre-market testing. Vacuum Casting also known as Urethane Casting or Polyurethane Casting can closely copy the master models for pre-production evaluation and low volume production for instant use before final injection-molded parts ready.Cast Urethane parts are also quickly and inexpensively without investing any metal tooling when quantities are only dozens, and can be delivered within weeks in most instances. With 20 years’ experience in new product development and vacuum casting China, WayKen specialist team offers accuracy form fit and highest quality Vacuum Casting service for prototype small numbers, seeking a competitive edge advance in product design and functionality.
SILICONE RUBBER MOLD
The Silicone Rubber Mold (also known as RTV mold) is created based on a master pattern. The master pattern is created by CNC machining or SLA. Silicone Rubber Molds is excellent chemical stability which offers minimal shrinkage which transfer fine details effectively from Master to Mold.The Silicone Mold life is directly related to the complexity of the cast part, generally 15 to 25 No’s before Degradation. Average cure times: 1 to 4 hours for small parts and 4 to 8 hours for big parts.
KEY FEATURES OF CASTINGS
Urethane casting parts can accurately match clients’ specification, no matter colors or surface finishes from Matt to Glossy. WayKen standardized operational procedures assure accurate part replication and consistent mechanical properties. Our Polyurethane Casting Technicians control all operational parameters: blending, de-gassing, stirring, preheating, casting and de-mold, so as to provide a standard tolerance on ± 0.15mm / 100mm, the highest precision can be ± 0.05 mm.
Our material selections of vacuum casting urethane always are HEI-CAST from Japan and AXSON from France. The properties of these Thermoset Plastics are similar to engineering plastics ABS, PMMA, PC, PP, PA, and POM. Casting products present from transparent, translucent toopaque and from soft rubber to hard plastic. In a variety also have High Impact and High Temperature (150 ℃) Fire Resistant UL94-V0 rated materials, and Glass Filled Resins.
