Yes, we have a special agent in Hong Kong, they will handle all shipping (Air, Sea, and Express) for us, it is much cheaper than shipping direct from Shenzhen. We also accept FOB Shenzhen if needed.

Q What is core and cavity for mold?

The plastic injection mold is composed of a cavity and a core. The cavity is a concave plate. The core is a convex plate. but now some mold cavity shape is very complicated, we can't identity cavity and core side, Normally cavity is fixed side and the core is moveable side with ejector pins.

Q  What is parting line(or parting surface) for mold?

Designed for the removal of the plastic product and the runner, the parting line (surface) is where the core meets the cavity, and usually locates at the largest section of a product.

Q  What is ejector pin?

The commonly used methods for ejection of plastic products include ejector pin, ejector sleeve, ejector blade and stripper plate. Since ejector sleeve and ejector blade are higher in price (8 to 9 times more expensive than ejector pin) and stripper plate is used for the ejection of thin barrel-shaped plastic products, the most commonly used is the ejector pin.

Q  What is the cooling for mold?

The cooling system is also known as the mold temperature adjusting system.Importance to adjust the mold temperature: Mold temperature plays an important role in determining the quality and molding cycle of a plastic product.

Q What is the lifter for mold?

The lifter is mainly used to form the internal undercuts of a molded plastic part, and at the same time it also offers ejection function. The mechanism features a simple structure but poor rigidity and a short travel distance.

Q What is the slider for mold?

Due to the special requirements of a product, the mold release direction of a particular part may not be consistent with the mold opening direction of the injection molding machine (product undercut), the slider is a mold mechanism that is developed to solve the issues with the undercut. The basic principle is to turn the vertical movement of mold opening / closing into a horizontal motion.
