What is an Auxiliary Machine and what role does it play in the injection molding process?

Auxiliary Machine refers to equipment used to assist in completing specific tasks during the main production process. In injection molding production, auxiliary equipment can not only improve production efficiency and ensure high product quality, but also optimize the entire production process and reduce manual intervention, thereby increasing production while reducing costs. The injection molding process involves heating and melting the plastic raw materials and injecting them into the mold through the injection molding machine to form the final product. In order to ensure the smooth progress of the injection molding process, various auxiliary equipment is often needed to provide support.

First of all, the quality of plastic raw materials plays a vital role in injection molding production, and the moisture content in the raw materials directly affects the effect of injection molding. In order to ensure the drying of plastic raw materials, the commonly used equipment is the dryer. The dryer removes moisture from the plastic raw materials by heating and air circulation to prevent the plastic from being difficult to melt due to excessive moisture, which in turn affects the quality of the product. If the plastic raw materials are not fully dried, bubbles may be generated during the injection molding process, affecting the surface quality and even causing the product to crack.

Secondly, during the injection molding process, different types of plastics or colorants often need to be mixed to ensure the uniformity and color consistency of the finished product. At this time, a mixer is needed. The mixer can effectively mix different batches or types of plastic materials in a set ratio to ensure that the raw material composition and quality used in each injection molding process are consistent. Especially when producing products that require multiple colors or materials, the role of the mixer is more important.

In addition, during the injection molding process, the cooling of the mold and the finished product is a very critical link. If the cooling speed is too fast or too slow, it will affect the quality and precision of the product. In order to maintain the appropriate temperature of the mold and the finished product, a cooling tower is often required. The cooling tower helps the injection mold to cool down quickly by providing continuously circulating cooling water, thereby ensuring the dimensional accuracy and surface quality of the molded product. It not only accelerates the cooling process, but also improves production efficiency and reduces product deformation and dimensional errors.

The automatic feeding system is also one of the indispensable auxiliary equipment in injection molding production. In the injection molding production process, the continuous supply of raw materials is very important. The automatic feeding system can automatically transport the raw materials from the silo to the injection molding machine, avoiding errors in manual operation and ensuring stability and continuity in the production process. This not only reduces the tediousness of manual operation, but also improves production efficiency and reduces labor costs.

During the injection molding process, the product needs to be quickly removed from the mold after molding, and the mechanical arm (or robot arm) plays a vital role. The mechanical arm can automatically remove the molded product and quickly and accurately carry out the next process, avoiding damage or inaccuracy that may be caused by manual removal. The application of the mechanical arm has greatly improved the degree of automation of production, reduced human operation errors, and improved production efficiency, especially in large-scale production. Its advantages are particularly obvious.

In addition, the hot runner system plays a key role in temperature control during the injection molding process. It accurately controls the temperature of the plastic melt to avoid the solidification of the plastic due to the temperature drop before injection into the mold, ensuring that the melt is always in a suitable flow state. The application of the hot runner system makes the injection molding process more efficient, reduces the generation of waste, and saves raw materials.

The mold temperature controller is an important device for controlling the mold temperature in injection molding production. During the injection molding process, the temperature of the mold needs to be kept within a certain range to ensure the fluidity of the plastic and the life of the mold. The temperature controller can accurately control the temperature of the mold to avoid injection defects caused by too high or too low temperature, such as warping and cracking of the product.
