DWV 180 Degree Elbow Injection Mould - Spark Mould
This innovative 180-degree elbow mold is designed to solve the production problems of PVC elbows with long straight sections and difficult demolding. The uniqueness of this mold lies in its foldable core technology, which allows the mold to easily ejection while maintaining high-precision molding. This mold is suitable for PVC materials and has good corrosion resistance, wear resistance and service life.
DWV PVC Hub Tee Fitting Mold Supplier - Spark Mould
This Tee joint mold adopts angle side core pulling mechanism, efficient production capacity and perfect adaptation to PVC materials, making it the preferred solution in the field of Tee-type pipe joint production. The angle pin side core pulling mechanism can save space and adapt to smaller machines. It ensures the stability and accuracy of the mold during the molding process.
Factory Custom Plastic Pipe Fitting Mold - Spark Mould
The automatic unscrew thread mold is suitable for all pipe fittings with internal wall threads. We use an automatic unscrew thread mechanism driven by a hydraulic motor and gear transmission. This allows the threads to be ejection smoothly without damaging the threaded parts. Compared with traditional manual or mechanical stripping methods, the automatic thread stripping mechanism is not only easier and faster to operate.
J Bend PVC Pipe Fitting Mold - Spark Mould
The J-type elbow has two directions of ejection mechanism, one is the hollow structure inside the tube, and the other is the lateral protruding hole. Therefore, we adopted the design of collapsible core and angle pin core pulling mechanism. It not only ensures the precise molding of the inner cavity of the product, but also effectively improves the adaptability of the mold.
Plastic End Cap Mold - Spark Mould
The tube end cap injection mold adopts an automatic unscrew thread mold mechanism, which greatly optimizes the mold stripping process. The automatic thread stripping mold mechanism has a high degree of stability and reliability, which can ensure that each demoulding is accurate, further ensuring the quality and consistency of the tube end cap products. It can also reduce manual intervention and improve production efficiency.
90 Degree Elbow Mould - Spark Mould
The 90-degree joint has core pulling in two directions. We have designed a folding core and angle pin core pulling mechanism. To make the product release from the mold smoothly ,we designed and manufactured three pivoting core inserts. It depends on the arc length of the elbow and it has two straight area. The only disadvantage of this structure is that the mold core cannot carry cooling. Only used the method of external cooling .
