Silicone bonded with plastic in moulding is a common manufacturing technique used by Great, also known as silicone over moulding process.

It consists of the following steps: firstly, the main part of a plastic product is made through one shot plastic injection moulding; then, silicone material is injected into certain areas of the plastic part to wrap it, forming an overmoulding effect; and lastly, the silicone overmoulded plastic product is formed after a curing process.

The advantage of the silicone overmoulded plastic process is that it can organically combine silicone and plastic together, giving full play to the advantages of both. Silicone has good flexibility, elasticity, tear resistance, insulation and waterproof performance, while plastic has high rigidity and structural strength. Through this overmoulding process, the product can have both the rigidity and structural strength of plastic, and the soft touch and excellent performance of silicone, to meet the needs of different fields.

This process is widely used in electronics, medical, automotive, toy and other industries. For example, in electronic products, silicone-overmoulded plastic molding can provide good waterproof performance and shock resistance; in medical devices, it can provide comfortable touch and excellent durability; in automotive parts, it can provide good sealing and high temperature resistance. These advantages make silicone-overmoulded plastic molding a popular manufacturing process.
