Silica gel has good simulation, strength and very low shrinkage. Here I will introduce you to the process of silicone mold production steps.

 

one. Shouban model prototype surface treatment: RP prototyping prototype rapid prototyping in the stacked section between the general presence of step lines or cracks, the need to be polished and seepage and strengthening treatment, in order to improve the Prototype surface smoothness and moisture resistance and Heat resistance and so on. Only the prototype plate surface smooth enough to ensure that the production of silicone mold surface roughness, and thus ensure that the product has a refurbished surface with high surface quality and easy to remove from the silicone mold.

 

Two. Production of frames and fixed Prototype Prototype: Prototype according to the prototype geometry and the use of silicone mold design casting box shape and size, the size of the frame should be moderate. It is very important to determine the location of the parting surface and the gate before fixing the prototyping. It is very important to determine the location of the parting surface and the gate. It has a direct impact on whether the casting mold can be successfully released and the casting quality of the hand model is good Bad. When the parting surface and the gate are selected and processed, the prototype of the palm plate is fixed in the frame.

 

three. Silica metering, mixing and vacuum degassing: The amount of silica gel should be based on the production of the size of the box and the exact measurement of the density of silica gel. Will measure a good amount of silicone into the appropriate proportion of hardener, after mixing vacuum degassing. Degumming time should be based on the degree of vacuum to grasp.

 

Four. Silicone Casting and Curing: Silica gel vacuum degassing after pouring has been fixed prototype box. In the casting process, should have some skills. After pouring silica gel, to ensure that the cavity filling intact, vacuum degassing again. The purpose of defoaming is to extract the gas mixed with silica gel in the pouring process and the gas sealed in the prototype cavity. The defoaming time should be longer than the defoaming time before pouring. The specific time should be based on the selected silica gel The material's operational time and hand prototype size may be. After degassing, silicone mold can be hardened or heat hardening. Hardening hardening can shorten the hardening time.

 

Fives. Demolition of the frame, the knife cut open the mold and remove the prototype Prototype: When the silicone mold hardened, you can remove the mold box and remove runner sticks. Referring to the markings of the prototype parting surface, the prototype is taken out and the prototype of the palm plate is taken out. The cavity of the silicone mold is cleaned as necessary, and then the resin mold made of the resin can be utilized to manufacture the resin or plastic product in a vacuum state.
