RTV – Vacuum Casting

Room Temperature Vulcanization (RTV) is the fastest, most accurate, and least expensive way to create up to a dozen or so duplicates of a prototype parts. RTV Vacuum Casting Service uses the rubber molds which can aptly duplicate details and textures present on the original part. After the RTV Vacuum Casting are completed, they are then typically used to produce limited quantity polyurethane castings with a wide variety of material properties.

At 3E-PD, we tend to do RTV vacuum cleaning, RTV Vacuum Casting which is a highly versatile technology capable of producing parts in a range of polyurethane (PU) resins and cast nylon. It creates replicates and replaces engineering polymers for prototypes and end-use parts. This RTV Vacuum casting technique is ideally suited to low volume batch production when injection moulding is not cost beneficial. These RTV Vacuum casting services can mimic production parts in material properties, thermal properties, colors, and surface textures, and can as well be machined, sanded, glued, and painted readily. Casting methods include:

Gravity casting: The liquid urethane is poured into the RTV molds and the method depends on gravity to feed the material into the cavity of the tool.

Vacuum Casting: Vacuum Casting Molding is a technology used for producing functional thin-walled complex prototypes parts in plastic materials which stimulate Nylon, Polycarbonate and other production materials.

Thin Wall Reaction Injection Molding: It can produce copies of rapidly prototyped parts at a rate of about three or four per hour.

WHAT WE OFFER

Tool Material: Steel & aluminum (common tool steel we use is P20, we can use higher grade steel if necessary)

Molding Material: ABS, PP, PC, PC/ABS, POM, PMMA, PA, PA GF, PBT, PBT GF, PPS, PTFE…and so on. We can work on the most of the plastic material available in the market. If you request special material, you can get a confirmation from us by email.

Lead time: Typical projects will take about 1.5 weeks to 3 weeks.

Advantage: Real material with different surface finish available (Normal technical polish, High gloss & Texture), quality standard close to mass production. Cost efficient for the quantity 100 up to 10000 pieces.

Disadvantage: Too costly if you only request a few pieces.
