The advantages of hollow forming are obvious, not only can it reduce the weight of the product, improve its strength and durability, but it can also save raw materials and production costs. In addition, the hollow formed product has a smooth surface, stable quality, and is easy to process and assemble, greatly improving the appearance and quality of the product. Therefore, hollow forming has been widely used in industrial production.

The process flow of hollow molding generally includes steps such as mold design, raw material preparation, injection molding, cooling, and demolding. Design the mold according to the shape and size requirements of the product. Then prepare the required plastic or metal raw materials and heat them to soften them. Next, inject the softened raw material into the mold to fill the entire cavity. Within a certain period of time, the raw materials will form the desired hollow shape inside the mold. Then, cool the plastic or metal raw materials to harden and shape them. Open the mold, take out the finished product, and complete the entire manufacturing process.

How to reduce the defect rate of hollow formed products in the production process in Dalian?

We need to do a good job in screening and processing raw materials. Choosing high-quality raw materials is the foundation for manufacturing high-quality hollow molded products. Strict screening and processing of raw materials can effectively reduce defects that occur during the production process, such as controlling the humidity and quality of raw materials, preventing raw materials containing impurities, fibers, and other foreign objects from entering the production line, and avoiding adverse effects on the quality of finished products.

Secondly, strengthen production process control. Optimizing the production process parameters of hollow formed products, such as temperature, pressure, time, etc., ensures the stability and accuracy of each process step, improves the stability and reliability of the production line, and helps reduce the occurrence of product defects. At the same time, establish a sound production record and testing system, strictly implement various operating procedures and standards, and ensure that product quality meets regulatory requirements.

Thirdly, strengthen equipment maintenance and management. Regularly conduct equipment maintenance and upkeep to ensure the normal operation and good condition of production equipment, improve production efficiency and product quality. Technological transformation and updating of production equipment, adopting advanced automation control technology and equipment, can further reduce the defect rate of products.

To achieve the airtightness of hollow formed products, comprehensive consideration should be given to design, material selection, processing technology, and quality control to ensure that the products have good airtightness performance. Only in this way can the requirements for airtightness of the product be met during use, and the reliability and service life of the product be improved.

Hollow forming is a very effective manufacturing process that can reduce product weight and improve strength by forming hollow structures inside the product. It has great application prospects and development potential. Hollow forming is commonly used in fields such as plastic and metal products, and is one of the common manufacturing processes.
