This on-site production video fully presents the whole precision injection molding process of car door lock bases. The complete production solution adopts self-developed Konger K-TEC400 high-performance injection molding machine from Ningbo Konger Machinery Co., Ltd. Equipped with an efficient 4-cavity mold, it mass produces core car door lock base parts, satisfying both high output and high-precision molding requirements. The product is made of PC+ABS engineering plastic alloy. It combines high strength, impact resistance and thermal stability of PC with easy processing, fine surface texture and stable dimension of ABS, making it a mainstream material for automotive interior and exterior parts. Featuring outstanding weather resistance, deformation resistance and structural toughness, the material adapts to complex driving conditions and prevents cracking, aging and distortion in long-term service, fully meeting assembly accuracy and durability standards of door lock bases. Tailored for molding characteristics of PC+ABS alloy, Konger K-TEC400 injection molding machine is equipped with precise temperature control system, stable hydraulic control system and intelligent parameter adjustment module. It accurately manages melt fluidity, injection pressure and holding time. Ideal for multi-cavity mass production, it ensures even melt filling and minimizes shrinkage, burrs and internal stress, delivering products with unified dimension, smooth surface and qualified structure. Supported by 4-cavity high-efficiency mold and steady continuous operation, production efficiency is greatly improved with shorter molding cycles, helping auto parts manufacturers cut costs and raise profits. Committed to R&D and manufacturing of injection equipment, Ningbo Konger Machinery’s K-TEC series machines serve auto parts, home appliances, industrial components and more. Customized solutions for multi-cavity molds and special engineering plastics are available, offering solid equipment guarantee for mass production of precision plastic products.
