Hollow forming is a common and effective manufacturing process widely used in various industries. By mastering this technology, high-quality, efficient, and cost-effective products can be produced to meet market and customer demands. I hope that in the future, hollow forming technology can continue to develop and improve, bringing more convenience and innovation to our lives and industries.

Cooling is an indispensable part of the injection molding process, and proper cooling can effectively control the shrinkage rate and internal stress of the product, thereby improving the quality and dimensional stability of the product. Usually, cooling water pipes or air ducts are installed in the mold to lower the temperature of the product and accelerate the solidification and hardening process through water or air. A good cooling design can improve production efficiency, reduce costs, and also reduce defects such as warping and cracking of products.

What are the characteristics of Dalian hollow formed products?

1、 Hollow forming can produce products with complex shapes. Due to the fact that hollow molding involves injecting molten plastic into a hollow shaped mold under pressure, various complex hollow products can be manufactured, such as special-shaped bottles, curved pipes, etc.

Secondly, hollow forming has high production efficiency. The production process of hollow molding is simple and fast, just inject the molten plastic under pressure into the mold, and then cool it to form. Therefore, the production efficiency is very high, suitable for large-scale production.

Thirdly, hollow formed products have excellent physical properties. Due to the stable structure, smooth surface, and uniform density of hollow formed products, they have good physical properties, such as high compressive strength and excellent sealing performance.

Fourthly, hollow forming can achieve the formation of various materials. Hollow forming is not only suitable for various plastic materials, but can also be used to shape other materials, such as silicone, rubber, etc., thus having good material adaptability.

The process of hollow forming is usually divided into several steps. We need to design and manufacture a mold that is suitable for the mold. This mold can be made of metal, plastic, or other materials and has the desired shape and size of the product. Next, inject the molten material or chemical into the mold and form a hollow structure in the shape of the mold. Once the material cools and solidifies, the finished product can be removed from the mold and further processed or assembled.

Hollow forming is a common manufacturing process commonly used to produce hollow or hollow products. This technology is widely used in the production process of plastic products, such as toys, household items, packaging materials, etc. The process of hollow forming includes multiple steps such as raw material preparation, mold design, injection molding, cooling, demolding, etc. Each step requires precise operation and control.
