Customized Various Pipe Fitting 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.
Custom Injection Mould Fitting 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 .

Spark Mould offers high-quality, durable products and a wide range of options to meet the needs of its customers, allowing them to find first-class solutions for their "Plastic Pipe Fittings Mold".

Multi-Cavity Injection Mold: Design, Productivity & Cost-Benefit Analysis
Multi-cavity injection molds represent a pinnacle of manufacturing efficiency in the plastics industry, enabling the simultaneous production of multiple identical parts within a single molding cycle. This advanced tooling technology is indispensable for high‑volume applications across automotive, medical, electronics, and consumer‑goods sectors, where it delivers dramatic reductions in per‑part cost and cycle time while maintaining stringent quality standards.
Hot Runner Mold Technology: Design Principles, Thermal Management, and Cost-Benefit Analysis
A hot runner mold is an advanced injection molding tooling system designed to keep the polymer melt in a liquid state throughout the runner system. By utilizing an internally heated manifold and precisely controlled temperature zones, it injects molten plastic directly into the mold cavity. This eliminates the cold runner waste associated with traditional molds, significantly reducing material costs, shortening cycle times, and improving the dimensional consistency of high-volume plastic components.
Automatic Unscrewing Mold Technology: Design Principles, Applications, and Troubleshooting
Automatic unscrewing molds represent a sophisticated subset of injection molding tooling, specifically engineered for producing threaded plastic components with internal or external threads. Unlike conventional molds that rely on manual disassembly or secondary operations, unscrewing mechanisms integrate directly into the mold structure, enabling seamless, high‑volume production of precision‑threaded parts.
Thin-Walled Structures in Plastic Injection Molding: Design Challenges, Material Selection
Thin‑wall injection molding—defined as producing plastic parts with wall thicknesses below 1.0 mm and flow‑length‑to‑thickness ratios exceeding 100:1—has become a critical enabling technology for lightweight, material‑efficient components in packaging, automotive, electronics, and medical industries. The drive toward thinner walls reduces material consumption, shortens cycle times, and lowers part weight, but it also introduces formidable engineering challenges: rapid heat loss, high injection pressures, increased shear stress, and heightened sensitivity to processing variations.
