Due to the fact that the hot runner does not generate "garbage", there is no problem of handling "garbage". 'Garbage' means a waste of resources, while hot runner systems are low-carbon products that do not produce harmful environmental factors.

Due to the wide variety of plastics and often varying colors, the accumulated material heads during the injection molding process must be classified for dehumidification, drying, and sealed storage. At the same time, the noise generated by crushing can also have adverse effects on the environment.

In summary, applying the hot runner in the 3-plate mold has the following advantages:

1. The material head is easy to remove and can reduce the stroke of material head removal;

2. During injection, the plastic flow is relatively average, and the operating conditions of each injection point can be controlled separately, making plastic injection easier;

3. It saves on the cost of plastic materials and labor costs.

Hot runner saves plastic and improves efficiency

1. Using traditional cold flow channels may result in the generation of cold material heads, leading to additional costs. For example, if the cold material head accounts for 68% of the waste rate (during manufacturing, 1kg of material can only produce 320g of product, while the remaining 680g is cold material head), although the cold material head can still be recycled, due to factors such as human factors and the mixing ratio of recycled materials, in order to maintain normal operation, some cold material heads must be accumulated, resulting in financial stagnation.

2. The hot runner can be applied in the field of high-speed injection molding. High speed injection molding not only improves the efficiency of molding, but is also necessary for controlling the wall thickness of products such as cups and containers.

3. Applied in stacked molds. For products with thin walls and large quantities, such as CD shells, only a 15% increase in mold locking force is required, which can increase production by 80% within the same injection time.
