How to determine the number of plastic gear mold, Forwa precision plastic gear factory

As the name implies, there must be a variety of gears in the plastic gear reducer. According to the requirements of the reducer, the type, structure and number of gears in the gearbox will be different. Plastic mold is used in the production of plastic gear. The number of mold cavities is one of the important parameters of plastic mold. How to determine the number of mold cavities of plastic gear mold? There are several factors to consider.


1. We need to estimate the sales quantity of plastic gear boxes, or we need to ask the customer for a purchase plan. According to this plan, we will determine the capacity of the mold and finally determine the number of cavities of the plastic gear mold

2. The sales price of plastic gear box is closely related to the cost of plastic gear. The number of cavities of plastic gear mold determines the cost of plastic gear

3. The volume of plastic gear box is different, the reduction ratio is different, the size of plastic gear, the structure is different. The size and structure of plastic gear is an important factor to determine the number of plastic mold cavities

4. The precision of plastic gear depends on the mold. The higher the precision of plastic gear, the more difficult the plastic mold is to make. When designing the mold, we should consider the company's processing equipment and processing accuracy, so as to determine the number of cavities of plastic gear mold. Theoretically, high precision, the number of cavities will be better

5. The number of cavities of the plastic gear mold is affected by the clamping force of the injection machine. The number of cavities is too much, the injection amount of the machine is not enough, the clamping force is not enough, and the product defects processed will be many.


In short, the number of plastic gear mold cavity and capacity, cost, precision and other factors are a contradiction, comprehensive consideration of all factors, to choose the best plan is the necessary ability of mold design engineers.
