Car door RTV molding prototype

Vacuum Casting Process:

(1)Silicon mold preheating: heat the silicon mold to ****0°C, low mold temperature will cause the solidification incompletely and the bad physical property. Mold temperature is directly correlated with the size precision of the part.

(2)Casting material debubbling: respectively debubble the A and B liquid material in the vacuum tank for over *0 minutes.

(3)Injection molding: place the A liquid container and B liquid container in the vacuum tank. Stir the B liquid to debubble it for ***0 minutes, pour A liquid to B liquid and stir them , then inject the mixed A and B liquid to the silicon mold instantly. Resume atmosphere pressure of the vacuum tank within 1 minute from the beginning of the injection molding.

(4)Solidification: can release the mold after ****0 minutes solidification in the ****0°C thermo tanks. If necessary, it can take the second solidification for **3 hours in the ****0°C thermo tanks.

Applicable mold: make the soft silicon mold for the need of building prototype; the silicon mold life is ****0 times.

Casting material: PU. The used materials include Japan HEI-CAST and PELNOX,France AXSON.

Material physical property: similar ABS,similar PP,similar PC,similar PMMA (transparent),similar rubber (****0 shofd D),high-temp resistance (**0°C),fireproof material, etc.
