Mould For Motorcycle Helmet

Design Center

Design is the foundation of the product. A good design make the less of the repair work. Our design department has advanced CAD/CAE software, you can send us file like . We are the most suitable midwife of your great ideas! We can also put out a complete 2D and 3D mold blueprint according to the products provided by customers. You can send us the file in format of IGES, DXF, DWG, STP, X_T, PRT, etc or you could send us handwrite drawing or original sample is fine as well.

1.Cooling design

One of the most important aspects of mold design is the cooling system. It plays a critical role in the final part quality and productivity. In the molding process, long cooling times mean long cycle times. Short cooling times mean short cycle times.

Designing the right cooling system for the part will ensure optimum cycle times – the cooling time should not be limited by the cooling design it should be limited by the part design. Thicker wall sections will naturally have longer cooling times.

With proper cooling design, the mold will be capable of cooling down during the mold opening and closing stages. That means that the water channel distance from the molding surfaces and the distance between the cooling channels is critical.

2.Runner design

Runner design includes both cold runner and hot runner designs. Which is better? Both have their place and the one chosen depends upon the part design, molder capabilities, production quantities and mold price.

High volume, thin walled parts such as food containers use hot runners. To be competitive in thin wall high production quantities are necessary so fast cycle times and high cavitation is required. Hot runners can only achieve this.

To design molds for thin walled parts an injection mold designer who specializes in this type of tooling is required. Do not use a designer who only has experience with general-purpose moulding.

Cold runners are suitable for single cavity or multi cavity moulds with low to medium production requirements. Cold runners make colour change quick and easy as the runner is ejected between each cycle. Hot runners take time to change color.

The narrow and shallow portion of the runner as it enters the cavity is called the gate.


3.Ejection design

Part quality and productivity will suffer with a poorly designed ejector system. A good design will produce parts consistently and at optimal cycle times.

The mold will run fully automatically without the need for human intervention. This means the molder is operating efficiently and able to stay competitive by delivery on time and producing at minimal cost.

Common ejector systems use ejector pins, stripper rings or air pressure. The system used depends upon the part design, plastic material, mold price, production quantity requirements and machine capability.


A sprue is a channel through which a molten plastic material is being injected from the nozzle of the injection machine into the mold. It has a smooth, round, tapered wall to allow smooth material flow.

Runner System

Runners are channels where material flows from the sprue to the cavities.

Conventional Runner


Improved Runner


Balanced Runner: Resin is evenly distributed throughout the cavities. Volume and condition is the same. There is more material used because the total runner length is longer compared to the other two.


Hot Runner or sometimes called runnerless, can be more economical in high volume injection molding.
