Plastic injection molding machine It is a kind of equipment widely used in the production of plastic products. The injection speed is one of the important parameters that affect the injection process and product quality. The adjustment of injection speed has an important impact on the filling, molding and appearance quality of plastic products. Today, Liansheng Precision Horizontal injection molding machine This article will introduce the injection speed adjustment method of plastic injection molding machine and its importance in production.
The injection speed refers to the speed at which the injection molding machine injects molten plastic materials into the mold. In the injection molding process, plastic materials enter the injection cylinder through the screw, and then are injected into the mold cavity by the injection cylinder. The injection speed directly affects the filling effect of plastic materials and the molding quality of products.
Adjustment method of injection speed:
1. Control panel adjustment: modern plastic injection molding machines are usually equipped with digital control systems, and operators can directly adjust the injection speed through the control panel. On the control panel, there are usually buttons or knobs for setting the injection speed. The operator can gradually adjust the injection speed according to the product requirements and the characteristics of plastic materials to achieve the best injection effect.
2. Injection valve adjustment: some injection molding machines are also equipped with injection valves, which control the injection speed by adjusting the opening and closing degree of injection valves. The injection valve adjustment can more accurately control the injection speed and pressure in the injection process, which is helpful to improve product quality and production efficiency.
3. Oil pump regulation: the hydraulic system of the plastic injection molding machine is usually powered by the hydraulic pump, and the injection speed is controlled by adjusting the output flow of the hydraulic pump. By adjusting the flow of the hydraulic pump, the injection speed can be continuously adjusted and accurately controlled.
The adjustment of injection speed of plastic injection molding machine has an important impact on product quality and production efficiency:
1. Filling effect: proper injection speed can ensure that the plastic material is fully filled in the mold cavity, avoid defects such as cavities and short filling, and ensure the integrity and consistency of the product.
2. Molding quality: the adjustment of injection speed is also related to the appearance quality and dimensional stability of the product. Too fast or too slow injection speed may lead to problems such as product surface roughness, deformation or inconsistent shrinkage.
3. Production efficiency: reasonable adjustment of injection rate can improve injection cycle, speed up production, increase production output and reduce production cost.
4. Energy consumption control: proper injection speed can help optimize energy consumption in the injection molding process, reduce scrap rate, reduce production costs, and improve resource utilization.
The above is about the injection speed adjustment method of plastic injection molding machine. Do you understand it? I hope it will be helpful to you.
