This is a professional 1*1 cavity two-material overmold injection mould, specially developed for manufacturing remover scraper handles. It adopts dual material molding with rigid PP as the base and soft TPE for anti-slip grip. Equipped with large sprue and side gate runner system, the mould is built from premium 1.2344 hot work steel. Both core and cavity are processed with spark texture finish, presenting clear anti-slip grain on finished handles.
The overmolding process ensures tight bonding between PP and TPE without peeling or gaps. It perfectly combines structural rigidity and comfortable grip, ideal for mass production of hand tools, cleaning scrapers and remover tool handles.

Core Advantages
1. Professional PP & TPE Overmolding Design
This mould is customized for two different materials overmolding. Hard PP forms the supporting skeleton to bear force and ensure structural stability. Soft TPE is overmolded on the surface to provide non-slip, shock-absorbing and comfortable touching feeling. The optimized mould structure realizes strong adhesion between two materials, effectively avoiding delamination, warpage and separation during long-term use.
2. Large Sprue & Side Gate System
Designed with large sprue and side gate structure, it delivers smooth and steady plastic melt flow for both PP and TPE. It prevents insufficient filling, flow marks and air traps. The side gate will not damage the appearance and texture of the handle surface, ensuring neat and clean finished parts.
3. High Performance 1.2344 Mold Steel
The whole mould adopts high-quality 1.2344 mold steel with excellent heat resistance, wear resistance and deformation resistance. It can withstand continuous overmolding production of PP and TPE materials. The steel maintains stable precision after tens of thousands of production cycles, greatly extending the overall service life of the mould.
4. Spark Texture Finish on Core & Cavity
Core and cavity are finished with standard spark texture. The clear and uniform grain transfers perfectly to the plastic surface, forming effective anti-slip patterns on the scraper handle. The texture also enhances surface friction, making the tool grip safer and more labor-saving during operation.
5. Stable 1*1 Cavity Mass Production
1*1 single cavity layout features simple structure, easy operation and low failure rate. With reasonable cooling and exhaust design, the mould runs stably, shortens molding cycle and lowers defect rate. It is a cost-effective solution for medium and large batch production of remover scraper handles.
Application Range
This overmold mould is widely used to produce various hand tool handles, including adhesive remover scrapers, cleaning scrapers, putty knives, handheld maintenance tools and daily hardware grips. All finished products feature rigid support, soft anti-slip surface and stylish textured appearance.
