Double injection mould is a highlight among mould family. It attracted eyes of the world and open a new area in mould's history. It's believed that it will be a new direction of mould developing. In Wahshing we focus on two shot parts mould making and production, painting, thin wall and high precision parts mould making and production.
The characteristics of double injection mould
1. High precision and stable quality.
2. Good structure strength and durability.
3. Smaller gap between different color parts and better appearance than normal products.
4. Lower cost and promote added value as compounded parts.
Why we need double injection mould ?
1. Function requirements. Such as power switch, mobile keypad, keyboard indicator, car switches and so on. They require the parts with LED diaphanous.
2. Improve handle feeling. Some handheld products, they require to use rubber on handheld parts in order to make them more comfortable. Such as interphone cover, electric power tool handle, spanner, toothbrush handle, thermos cup and so on.
3. Make products more beautiful as decorate. Some goods need to make logo, and it will be excellent and you don't need to worry the logo will be rubbed off any more.
4. Parts of the products need to be electroplated. As we all know, only ABS and PSU's surface are electroplating among plastic family. We can set the resin as ABS in the parts that need to be electroplated and other parts us PC or some other material if parts or one side of the products need to be electroplated.
Double Inject Process
Wahshing’s double molding dies are uniquely created with two cavities in the same die, which allows a product to be produced in one injection cycle. The first cavity is used to case such features as letter or symbols, while the second cavity is used to form the outer shape of the product.The first layer injection nozzle moves forward. When the cavity plate close, the primary molding is cast. After casting is complete, the mold opens and the primary sprue and runner mover away. At this stage, the primary molding remains on the cavity gate.The cavity plate containing the primary molding rotates 180°The mold closes again and the secondary material is injected, filling the space between the primary and secondary cavities. At the same time, the additional primary injection is made. Once the filling is complete, the mold opens and the finished product is ejected.Bottom double injection molding:
