Cone Bottom PE Dosing Barrel Industry knowledge

What is the effect of temperature on Cone Bottom PE Dosing Barrel during rotational molding?

As a member of China's rotational mold manufacturing industry, Cixi Junyi Plastic Industry Co, Ltd. has been deeply involved in the field of rotational molding since its establishment, and is committed to providing customers with high-quality rotational molding products and solutions. Among our many products, Cone Bottom PE Dosing Barrel is deeply favored by the market for its unique conical bottom design and excellent performance. In the rotational molding process, temperature is a crucial factor, which directly affects the molding quality, physical properties and production efficiency of Cone Bottom PE Dosing Barrel.

1. The effect of temperature on the molten state of plastic
The core of the rotational molding process is to heat the plastic raw material to a molten state, and evenly coat it in the mold and cool it to solidify. Temperature is the key factor in controlling the molten state of plastic. For Cone Bottom PE Dosing Barrel, when the heating temperature is too low, the PE raw material is not fully melted, which will lead to poor fluidity of the plastic in the mold and difficulty in forming a uniform coating, which will affect the uniformity of the wall thickness and appearance quality of the product. When the heating temperature is too high, although the fluidity of the plastic is enhanced, the excessively high temperature will cause the plastic to decompose and discolor, and even produce defects such as bubbles and shrinkage holes, which seriously reduce the strength and durability of the product.

2. The influence of temperature on mold heating efficiency
During the rotational molding process, the heating efficiency of the mold directly determines the melting speed and molding cycle of the plastic raw material. Appropriate heating temperature can ensure that the mold reaches the required temperature in a short time, thereby accelerating the melting process of the plastic and shortening the molding cycle. Excessive heating temperature will increase energy consumption, and may also damage the mold material and shorten the service life of the mold. In the rotational molding process of Cone Bottom PE Dosing Barrel, we need to accurately control the heating temperature according to the material, structure and size of the mold to achieve an efficient and energy-saving molding process.

3. The influence of temperature on the cooling process
The cooling process is another important link in rotational molding. After the plastic is melted and evenly coated on the surface of the inner cavity of the mold, it is necessary to cool the plastic to solidify and mold it. Temperature also plays a key role here. Appropriate cooling temperature can ensure that the plastic maintains a stable shrinkage rate during the cooling process to avoid deformation and cracks. Reasonable cooling methods can also effectively shorten the cooling time and improve production efficiency. If the cooling temperature is too low or the cooling speed is too fast, it may cause internal stress inside the plastic, affecting the mechanical properties and dimensional stability of the product.

4. The influence of temperature on product quality
The influence of temperature on Cone Bottom PE Dosing Barrel rotational molding is multifaceted. It affects the melting state of the plastic and the heating efficiency of the mold, and is also directly related to the cooling process and quality of the product. During the rotational molding process, we must strictly control the temperature parameters of each link to ensure that they are in the best state. Only in this way can Cone Bottom PE Dosing Barrel products with uniform wall thickness, beautiful appearance and excellent performance be produced.

5. In order to cope with the influence of temperature on rotational molding, Cixi Junyi Plastic Industry Co, Ltd. has taken a series of effective measures.
Advanced temperature control equipment: Introduce advanced temperature control equipment to achieve precise control of the temperature of the heating chamber and mold, and ensure that the temperature fluctuation range is within the allowable range.
Optimize heating process: According to different plastic raw materials and mold structures, formulate scientific and reasonable heating process plans to improve heating efficiency and product quality.
Innovative cooling technology: Adopt innovative cooling technology, such as local air cooling, water cooling, etc., to shorten the cooling time, reduce the generation of internal stress, and improve product performance.
Strict quality control: Establish a complete quality management system, conduct all-round quality control of raw materials, molds, molding processes and finished products, and ensure that each batch of products meets customer requirements.
