The plastic packaging industry is experiencing rapid growth, with the demand for products such as bottle caps, bottle blanks, and spray pumps continuously increasing. Multi-chamber high-speed injection molds are becoming more widespread, and higher standards are being set for the precision, wear resistance, and interchangeability of core components such as screw thread cores, threaded sleeves, and rotating threaded assemblies. Dongguan Xuheng Precision Mold Accessories Co., Ltd. has been deeply involved in the field of bottle cap small screw thread mold accessories, continuously promoting the standardization of precision mold accessory design, taking into account both the demand for standardized ready-made products and non-standard customization, and empowering packaging mold enterprises to reduce costs and increase efficiency.

The small screw thread molds for bottle caps belong to high-cycle production molds. Every opening and closing of the mold, and every rotation and ejection of the threaded part, relies on the collaborative work of components such as screw thread cores, gear components, and threaded sleeves. If the screw thread tooth shape error or the unreasonable fit clearance occurs, problems such as incomplete bottle cap screw threads, ejection scratches, and burrs will arise, directly increasing the product defect rate during mass production. In the traditional model, many mold factories processed screw thread accessories by themselves, with limited processing equipment and detection conditions, poor interchangeability of parts, and long repair periods after component damage, which delayed the production progress of the injection molding line.

To address industry pain points, Xuheng Precision has accumulated years of project experience. On one hand, it continuously improves the standardization system of mold parts for bottle caps, bottle blanks, and spray pumps, sorts out common specifications to establish inventory, and customers can directly purchase ready-made products; on the other hand, it undertakes the customization of various non-standard drawings, optimizing screw tooth shapes, cooling structures, and material selection based on the number of mold cavities, injection molding cycles, and product materials, with processing accuracy reaching 0.002mm, ensuring that the dimensions of each screw thread part of the multi-chamber mold are uniformly sized, allowing for direct replacement after component damage, without the need for grinding and mold repair, and shortening the mold repair time.

The accessories related to the small screw teeth molds produced by the company include threaded cores, screw teeth sleeves, gear rotation components, shaft sleeves, positioning components, etc., which are suitable for various product molds such as beverage bottle caps, daily chemical bottle caps, pharmaceutical packaging bottle caps, and spray pump housings. During the production process, the grinding equipment ensures the processing accuracy of the threaded tooth shape, and multiple grinding processes optimize the surface smoothness, reducing the plastic product's demolding scratches; the heat treatment process is optimized to enhance the surface hardness of the parts, achieving a stable service life of over 1 million mold cycles. The inspection process uses two-dimensional and three-dimensional detection equipment to randomly inspect the screw tooth shape, coaxiality, and dimensional tolerances, ensuring that no substandard products are released from the factory.

The customers in the packaging mold industry include both large-scale standardized orders and the customized demands for irregular small batches brought by new product development. Xuheng Precision has established a "standard parts + non-standard customization" dual business model, with products covering medical molds, cosmetic molds, bottle core molds, plastic molds, and other supporting parts. After years of market expansion, the products have been exported to overseas markets such as Italy, Spain, the United Arab Emirates, Malaysia, and Thailand, and have been recognized by domestic and foreign mold manufacturers.

Under the industry trend, the iteration speed of packaging products is getting faster and faster. Mold enterprises need to shorten the new product development cycle. Xuheng Precision will continuously optimize the standardization database of screw teeth mold accessories, iterate the processing technology, and help the packaging mold industry achieve rapid component selection and rapid delivery, improving the production efficiency of the entire industry chain.
