A professional silicone vacuum casting service
Silicone vacuum casting is a prototype method. It takes a short
time to manufacture and the little cost is an advantage of it. In this
prototype casting methods, having a small probability for the failure of the
process. This method is able to manufacture more than twenty products by using
just one silicone mould. This material of the product includes PP, PC, PMMA,
ABS, flexible glue, silicone rubber, and resistant material.
Impacts of silicone vacuum casting
Nice Rapid is a service that provides silicone vacuum casting to
manufacture the products with a silicone mould. Vacuum casting can replicate
all the injection molding properties. It is mostly used to mold two parts of
polyurethane which are accessible in a vast range of grades, colours,
transparencies, and densities. The liquid polyurethane is haggard into the mold
that is held under the vacuum. It ensures the material without porosity which
means a tiny hole. It will through the cavity of the mold and it will not be
restricted by the pressure of air.
The polyurethane is held on the mold, so it
can pour into the mold and it runs under the force of gravity to rise up. This
runner is intended to provide a curtain of liquid polyurethane. It helps to
flow through the mold and up the risers. After this process, it will take some
time to fill the mold cavity and the vacuum will be equalized. The left of the
mold is closed to complete the curing time which takes 45 minutes to four
hours. After completion of the process, the part is ejected and excess
materials will be removed. There is a lot of risers to make sure that the mold
is evenly filled.
Service of silicone molding production
Nice Rapid completely carried out the service of silicone
molding production from mold, trimming, refining, assemblage with the most
proficient rubber vulcanizing equipment, the innovative R & D sprite,
strict quality control strong production capacity that makes us well to produce
the material of NR, NBR, EPDM, SIR, CR, SBR, FKM, PU, etc. In nice rapid, all
the raw materials can conform with ROSH, REACH and FDA, strictly enforce of
ISO-9001 to get international quality system certification. They maintain
high-quality cooperation with domestic and foreign companies.
Silicone moulding has two kinds of manufacture methods are
compression molding and liquid silicone rubber molding.
- In compression moulding use
rubber to manufacture the components and also using coating existing
tools. It has some advantages to mould the products that are making the
rubber to be strong; it is more malleable and less rigid compared to other
materials. There are three processes to produce rubber parts are
compression, injection, and extrusion of moulding. These three have their
own unique compensation than other methods.
- Liquid silicone rubber is a cured silicone that has high purity. It is pertinent to the production of silicone rubber products with some tremendous details and well accuracy. It has great stability and resistance of extreme temperatures of heat and cold, liquid silicone rubber is ideally suitable for production components.
