Plastic drum dedicated injection molding machine

Paint barrels, machine oil barrels, and commonly used packaging drums in the market are injection molded products that are produced by injection molding machines in one go. Depending on the purpose and quality requirements of the product, new raw materials, recycled materials, and modified fiber materials can be used, and added appropriately according to the process formula. Our company's TH630/SP and TH730/SP servo energy-saving injection molding machines are specialized in producing fast and precise servo energy-saving injection molding machines for injection molding round barrels. They provide stable quality and reliable performance for plastic product manufacturers such as paint barrels, machine oil barrels, and liquid fertilizer barrels across the country. From recommending equipment solutions to installing and debugging injection molding machines, to providing personnel training, it has played an initial constructive role for small and medium-sized enterprises across the country, and has also provided high-quality products for the upgrading of injection molding machine equipment for large enterprises.

Market prospects: The traditional packaging form is iron drums, and its production process and application are extremely mature. It is widely used in petrochemical products, food packaging, especially in specific packaging containers such as machine oil drums and paint drums. With the rapid development of the petrochemical industry, there is a trend for new packaging forms of plastic packaging containers to replace traditional metal containers. Due to their various advantages, they are more beneficial to plastic product manufacturers and end users.

Advantages and characteristics of injection molded round drums compared to iron drums:

1. The material of the iron drum is steel, which requires the steel plate to be flat, with uniform thickness. Compared with plastic drums, it has better chemical resistance and process performance, but the probability of leakage is higher. The material of plastic barrels is molecular plastic HDPP, which has the advantages of light weight, low cost, waterproof and moisture-proof compared to steel. Due to one-time injection molding, the probability of leakage is much lower than that of iron barrels. With the addition of modified materials and the improvement of injection molding technology, the barrel body has higher barrier properties, flexibility, and impact resistance than steel, which is sufficient to withstand the impact during packaging and normal transportation.

The manufacturing process of iron drums involves relatively complex technological processes, including sheet metal unwinding and leveling, welding edge treatment, barrel body welding, barrel body flanging, barrel body bulging, roll sealing assembly, barrel bottom cover forming and pre rolling, surface treatment, inner surface spraying, and outer surface spraying. The manufacturing of plastic barrels is relatively simple, and the surface printing treatment is also relatively simple and the appearance grade is relatively high. Production only requires injection molding process once, greatly reducing production costs.

3. The recycling and use of iron drums require steel smelting and recycling manufacturing, while plastic drums only need to be crushed, cleaned, and re injection molded before use. The cost of recycling is much lower than that of iron drums.

With the rapid development of the plastic industry and the continuous influx of various new technologies and plastic materials, plastic packaging barrels have complied with the national environmental protection development strategy in the packaging field, and their market share and influence will continue to increase.
