Rubber Injection Moulding Machine High Speed Silicone Baby Bottle Making Machine

 

Lack of glue or poor material refers to the incomplete or incomplete silica gel products after forming. In addition to the cause of the mold, it may also be caused by the following:

 


1. The weight of raw materials is not enough, so a skillful woman can't cook without rice;

2. The unreasonable design of the size and specification of the raw material makes it difficult for the raw material to flow and fill the mold cavity when it flows under pressure, resulting in the lack of glue. Generally, the cutting length of raw materials is too short or the thickness is too thick;

3. The discharge position of raw materials is not accurate, and the rubber cannot flow to the designated position;

4. Too long storage time of raw materials and too long storage time of cut-out materials lead to poor fluidity, and it is impossible to fill the full mold cavity under pressure;

5. If the mold temperature is too high, the raw material will be vulcanized before it reaches the designated position when it flows under pressure;

6. The molding pressure is insufficient, and the rubber cannot flow to the designated position;

7. Excessive addition of vulcanizing agent, raw materials have been vulcanized before reaching the designated position;

8. Product structure or mold problem, product structure is too complex

Precautions for manufacturing liquid silica gel mold:

1. shrinkage

Although liquid silica does not shrink in the mold, it typically shrinks by 2.5 to 3 after demoulding and cooling. The accuracy of shrinkage depends to some extent on the formulation of the compound. However, from a mold perspective, shrinkage can be affected by several factors, including mold temperature, temperature of compound release, pressure in the cavity, and subsequent compression.

The location of the injection point is also worth considering, as the shrinkage in the direction of composite flow is usually greater than that perpendicular to the compound. The shape of product size also has an effect on its shrinkage. Thicker products generally have smaller shrinkage.

2. parting line

The first step of the design of the injection mold for silicone rubber is to determine the position of the parting line. The exhaust is mainly achieved by a groove on the parting surface, which must be located in the area where the injected rubber finally reaches, so as to avoid the formation of bubbles and reduce the strength loss of the bonding joint.

Due to the low viscosity of liquid silica gel, the parting line must be accurate to avoid overflow. Even so, the dividing line is often seen on the final product. The liquid silica gel mold is affected by the geometrical dimension of the product and the position of the parting surface
