What Is Blowing Mould

The Development and Application of Blow Molding Technology

▪ Blow molding, also known as hollow blow molding, is a method of blowing the hot melt billet closed in the mold to form hollow products by means of gas pressure.
▪ The blow molding process began to be used to produce low density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used.
▪ The volume of hollow containers can reach thousands of liters, and some production has been controlled by computers. The raw materials suitable for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc.

The Progress of Blow Molding

▪ Material Preparation: Plastic pellets or granules are selected based on desired properties such as strength, flexibility, or color. These materials are typically polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET).

▪ Extrusion: The plastic material is melted and formed into a parison (hollow tube) using an extrusion machine. The size and shape of the parison are controlled to match the final product specifications.

▪ Mold Closure: The parison is placed in a mold cavity, and the mold is closed around it. The mold is designed to match the shape of the final product.

▪ Blowing: Compressed air is injected into the parison, causing it to inflate and take the shape of the mold cavity. The pressure of the air and the design of the mold determine the final thickness and dimensions of the product.

▪ Cooling: The molten plastic inside the mold cavity is cooled using air or water channels within the mold. This solidifies the plastic into the desired shape.

▪ Mold Opening: Once the plastic has cooled and solidified, the mold opens, and the newly formed plastic product (such as a bottle or container) is ejected from the mold.

▪ Trimming and Finishing: Any excess plastic (flash) around the edges of the product is trimmed off. Additional finishing processes, such as labeling or surface treatment, may also be applied depending on the final product requirements.

▪ Quality Control: The finished products undergo inspection to ensure they meet specified quality standards for dimensions, appearance, and performance.

▪ Packaging: Finally, the products are packaged and prepared for distribution and shipment to customers or retailers.

This process is widely used for manufacturing plastic bottles, containers, automotive components, and other hollow plastic products due to its efficiency and versatility in producing complex shapes.

Potential Factors Affecting The Efficiency of Blow Molding

▪ Mold design : The rationality of the mold structure, the shape and dimensional accuracy of the cavity, and the design of the exhaust system, etc. If the mold design is not good, it may lead to uneven expansion of the parison and poor gas exhaust, thereby prolonging the molding cycle.
▪ Mold material: The quality and performance of the mold material directly affect its service life and working efficiency. Materials with high strength, wear resistance, corrosion resistance, and good thermal conductivity can improve the durability and cooling speed of the mold.
▪ Cooling system: An effective cooling system can rapidly reduce the temperature of the plastic parison, accelerate its solidification and molding, and shorten the production cycle. Uneven cooling or low cooling efficiency will reduce the working efficiency.
▪ Mold closing accuracy: The low mold closing accuracy may cause leakage during the expansion of the parison, affect the product quality, and even result in rejects, increasing the production time.

▪ Parison quality: The temperature of the parison, the uniformity of thickness, and the fluidity of the material will all affect the effect and efficiency of blow molding.

▪ Blow molding process parameters: Including blowing pressure, blowing time, and blowing speed, etc. Unsuitable process parameters may cause the parison to fail to fully adhere to the mold or defects in the product, requiring multiple adjustments and retries.

▪ Equipment performance : The stability of the blow molding machine, the accuracy of the control system, and the efficiency of the drive system will all affect the working efficiency of the mold.

▪ Maintenance: Regular mold maintenance and upkeep, such as cleaning, lubrication, and repair of worn parts, can ensure that the mold is in good working condition and improve the working efficiency.

▪ Operator skills: The proficiency and experience of the operator, the ability to adjust process parameters, and the degree of compliance with the operation of equipment and molds will all affect the production efficiency.

Key Design Aspects Of blowing mold

▪ The key design aspects of a blowing mold are of great significance in achieving efficient and high-quality production of blown plastic items.
▪ Firstly, the precision and geometry of the mold cavity are critical. It must be accurately shaped to replicate the desired product form with exact dimensions and tolerances. The choice of mold materials is equally important. Materials that offer excellent heat conductivity, durability, and resistance to wear and corrosion are preferred to enhance the mold's lifespan and performance. The distribution and configuration of the air injection points and vents are vital for uniform inflation of the plastic material and efficient air escape, preventing any deformities or voids in the final product.

▪ Additionally, the surface treatment of the mold cavity influences the surface finish and texture of the blown plastic, ensuring a smooth and aesthetically pleasing outcome. Last but not least, the mold's locking and sealing mechanisms need to be robust and reliable to withstand the pressure during the blowing process and prevent any leakage or flash, thus guaranteeing the quality and consistency of the produced parts.
