Toy Industry

Finally, you will also find that certain toy products are made using silicone injection molding. The soft and elastic characteristics of silicone make it suitable for many small toys such as Barbie dolls, baby toys, and care products.

Silicone Injection Molding Steps

Material Preparation
Select the appropriate liquid silicone material, and formulate and adjust it according to the product requirements. Ensure the accurate preparation and proportioning of the material.

Preheating
Control the temperature of the injection molding machine's barrel to be below 25 degrees Celsius to ensure smooth flow and proper filling of the silicone material into the mold.

Mold Preparation
Prepare the appropriate mold, including steps such as cleaning the mold and applying mold release agent, to ensure smooth demolding of the product.

Silicone Injection Molding
Inject the liquid silicone material (AB glue) into a static mixer and then transfer it to the injection device. During the injection process, the material is injected into the heated mold.

Mold Filling
By applying the appropriate injection pressure and speed, the liquid silicone fills the entire mold cavity. The mold temperature should be evenly heated to ensure a stable flow of the silicone material within the mold and prevent issues such as incomplete filling.

Curing
Once the silicone has been filled into the mold, the silicone material inside the heated mold begins to cure and harden.

Demolding and Post-Processing
After a sufficient curing time, the mold is opened, and the finished product is removed. Post-processing of the product may include trimming edges, removing burr, and cleaning, etc.

FAQ

Q: Is Silicone Injection Molding More Expensive Than Traditional Molding?

A: While the initial investment is higher, it reduces waste and labor costs, making it more cost-efficient over time.

Q: Can Silicone Injection Molding Be Used for Medical Devices?

A: Yes, it is widely used for medical implants, surgical tools, and other healthcare applications due to its biocompatibility.

Q: How Long Does the Silicone Injection Molding Process Take?

A: It varies based on product complexity but typically takes a few minutes per cycle for mass production.

Q: What is the silicone injection method?

A: Silicone injection molding is a highly efficient method for manufacturing silicone products which includes three types: single shot injection, insert molding, and two-shot injection. The process involves injecting raw liquid silicone material into the mold and shaping it under high pressure.

Q: What is the influence of mold temperature on the silicone injection - molding process?

A: If the mold temperature is low, the vulcanization time is long; if the mold temperature is high, the vulcanization time is short. Generally, the mold temperature is controlled at a minimum of 150℃ and a maximum of 180℃. The vulcanization time is also related to the product size. The smaller the product, the shorter the vulcanization time; the larger the product thickness and the mold, the longer the vulcanization time.

Q: What problems should be paid attention to in mold design for silicone injection molding?

A: It is necessary to consider the characteristics of the injection - molding process, such as the fluidity and curing shrinkage rate of liquid silicone. The mold should use corrosion - resistant materials (such as stainless steel) and design a reasonable exhaust system to avoid bubbles affecting product quality, and avoid problems such as insufficient injection or flash.
