About vacuum casting low volume production
Once getting the master model, one can build a female silicone mold with certain elasticity by making
use of a bicomponent silicone rubber in normal temperature, then to cast the target product in vacuum
casting machine through vacuum casting.Up to now,It is the most used prototype copying method in
the world .
Features of vacuum casting low volume production:
l There are various kinds of materials can be used for silicone mold:ABS-LIKE,PP-LIKE,PC-LIKE,PMMA-LIKE,etc,different materials with different specifications;
l And apart from the variety of materials,customers can choose the transparency,hardness according
to their specified demand.Whats more,colors can be added into materials when producing silicone
mold products;
l The precision of vacuum casting prototype is +/-0.3mm;
l The minimum thickness of casting products is 0.5mm,best thickness range:1.5-5mm.
l The silicone mold life is not so long,one pair of silicone mold can cast 8-20pcs products at most,suits
best for low volume production.
Silicone mold vacuum casting process:
- -- -- -- -- -- -- -- -- - -- -- -- -- -- -- --- -- --- -- -- -- -- --
1.Prototype making. To make the prototype via cnc machining or 3d printing or SLA/SLS;
2.Prototype checking and handling. Inspect the prototype size and structures ,craftsman handle it ,
to remove any marks or deburs ensuring the surface very good;
3.Silicone mold building. With the finished prototype,casting master to build the silicone mold;
4.Mold curing. To cure the mold in oven under 40 centigrade degree for about 12 hours;
5.Mold splitting. Take the mold out,prune it and split the mold along the parting line,take the prototype
out of the mold;
6.Mold preheating. Put the mold into the oven and preheat it under 70 centigrade degree;
7.Vacuum casting. After preheating ,put the mold into vacuum casting machine ,pour the resin into the
mold through the sprue after 5-10min vacuuming;
8.Solidifying Forming. In the end,to put the has been cast into the oven to solidify the resin under 70
centigrade degree.
The curing time differs with materials ,normally between 40-90min,after solidified ,take the silicone mold out and get the cast part out ,to clear the Fragment and the gate,
so the vacuum casting prototype is finished .
To meet customer's willing of getting small batches testing prototypes in a short time ,EbyTon
purchased a large advanced vacuum casting machine and big sized oven,using imported materials ,t
o best guarantee the quality of casting products.
