How do they make plastic bottle caps?

  Plastic screw caps, injection molding screw caps, and toilet screw caps are important components of plastic bottle packaging. These caps provide the seal necessary to preserve the contents of the bottle.
  The manufacturing process for plastic bottle caps involves injection molding, a common method used to mass-produce plastic parts. The process involves melting thermoplastic resin pellets and injecting the molten plastic into a mold cavity under high pressure. Once the plastic has cooled and solidified, the mold is opened, releasing the newly formed plastic part.

  Injection molding machines come in different sizes and configurations, depending on the size and complexity of the plastic parts being produced. Mingsanfeng Cap Mould Co.,Ltd has a mold workshop equipped with various types of molding machines to suit different types and sizes of caps. With over two decades of experience, the company has honed expertise in the design and production of high-quality bottle cap moulds.

  The company’s team of engineers, senior mold engineers and technicians are proficient in computer-aided design (CAD) software to create custom molds to meet customers’ specific requirements. Molds are made from high-quality steel and machined to precise tolerances to ensure consistency in size, shape and function.

  After the injection molding process is complete, the plastic caps must go through an additional finishing step. These steps may include trimming excess plastic, adding a liner or seal to the cap, and printing a label or logo on the cap. Sanfeng Cap Mold Co., Ltd. can also provide these services to ensure that the caps meet the specific requirements of customers.
