In the plastic packaging industry, the manufacturing of molds for large containers such as edible oil bottles imposes extremely high requirements on the precision, strength, and stability of the mold base. As the "skeleton" of the mold, the quality of the mold base directly determines the mold's service life, production efficiency, and the dimensional consistency of the final product. Among numerous mold base manufacturers, Changhui Company has emerged as a leading supplier for mold bases used in large injection molds, such as those for edible oil bottles, thanks to its profound technical expertise, advanced production capabilities, and stringent quality control.
Professional Capabilities and Technical Advantages
Changhui Company specializes in the design and manufacturing of various medium and large-sized high-precision mold bases, with particular expertise in the field of large plastic mold bases. Its mold bases possess the following core characteristics:
- High Precision: Utilizing high-precision inspection equipment such as imported coordinate measuring machines (CMMs), the company ensures strict control over the dimensional tolerances of all mold base components. For key mating surfaces, precision can be controlled within ±0.01mm, ensuring the dimensional stability and sealing performance of edible oil bottle molds under long-term high-pressure injection molding conditions.
- High Strength and Excellent Thermal Stability: The company uses premium mold steels (such as P20, S50C, 2738, 718, etc.) combined with advanced heat treatment processes, endowing the mold bases with outstanding pressure resistance, deformation resistance, and thermal stability. This enables them to withstand high-temperature, high-pressure injection molding environments, thereby extending the mold's service life.
- Large-Scale Machining Capabilities: The company operates large CNC machining centers with travels of X-axis 3500mm, Y-axis 2500mm, and Z-axis 1500mm, with a machine load capacity of 30 tons. Equipped with specialized machinery like deep-hole drilling machines, the company can efficiently complete the integrated machining of mold bases for large container molds, such as those for edible oil bottles, ensuring structural rigidity and consistent precision for large mold bases.
Manufacturing System and Production Capacity Assurance
Changhui Company has established a complete mold base manufacturing ecosystem, providing end-to-end assurance for edible oil bottle mold customers—from materials to finished products:
- Full-Process Precision Machining: From cutting and rough milling to fine milling, deep-hole machining, and template fine grinding, each process is carried out using more than 50 advanced CNC machining centers. The entire process strictly adheres to the ISO9001 quality management system, ensuring machining precision and consistent quality.
- Raw Material Supply Chain Advantages: The company maintains a long-term inventory of forged materials like P20 and S50C, as well as various premium domestic and imported mold steels. This not only shortens delivery lead times but also allows the company to provide material processing services according to customer requirements, helping clients save on procurement and preprocessing time.
- Scalable Delivery Capacity: With over 120 production machines and a professional team of more than 300 people, the company's monthly production capacity exceeds 1,500 mold base sets. It possesses the capability to respond quickly to orders for large, high-precision mold bases, meeting the dual demands of edible oil bottle mold customers for both volume and delivery timelines.
