48 cavity PET needle valve cap mould: Efficient and Precise, Empowering the packaging industry to upgrade

The 48 cavity PET needle valve bottle cap mould is a core equipment designed specifically for high-speed packaging production lines such as beverages and daily chemical products. It adopts a needle valve hot runner system, which precisely controls the flow of molten metal through pneumatic or hydraulic driving of the valve needle, achieving synchronous filling of the 48 cavity and effectively eliminating defects such as melting marks and burrs on the surface of the bottle cap, ensuring sealing and appearance quality. The layout of the mould cavity is independently locked in each cavity to ensure that the concentricity of the mould is ≤0.05mm. It is compatible with international standard bottle mouths such as 28mm and 30mm, and has a wide range of compatibility.

The optimization of materials and processes is the guarantee for the long life of molds. The core components are made of original preheating treatment special mould steel, which has a hardness of HRC48-50 after vacuum quenching treatment. Combined with the P20 mould frame's electroplated anti-corrosion treatment, it can withstand more than 3 million injection molding cycles. The hot runner system is equipped with original German Hotset heating elements and an intelligent PID temperature control meter, achieving precise temperature control of ± 1 ℃, avoiding material degradation caused by temperature fluctuations, and extending the service life of the mould.

With the pursuit of lightweight and sustainability in the packaging industry, 48 cavity moulds are developing towards ultra-thin walls and high toughness. For example, using a new type of nanocomposite material for cap moulds can reduce wall thickness to 0.2mm and material usage by 20% while maintaining sealing. In addition, combined with industrial Internet technology, intelligent temperature control and remote diagnosis functions of moulds will become the standard configuration

The mould material is made of an imported S136 stainless steel core and P20 mould frame, with a surface treated with hard chrome plating, which improves wear resistance by 30% and has a lifespan of over 5 million moulds. Its spiral circulating cooling water channel works in conjunction with the external cooling system, shortening the moulding cycle to 15-17 seconds and increasing efficiency by 40% compared to traditional moulds. In addition, the hot runner temperature zoning control technology avoids problems such as whitening and warping of the bottle cap top, and the product qualification rate remains stable at over 99.5%.

The mould supports customized development and is widely used in fields such as mineral water, carbonated beverages, seasonings, etc. With the advantages of high efficiency, stability, and low consumption, it has become an ideal choice for packaging enterprises to reduce costs and increase efficiency.

Building on these advantages, Taizhou Qihong Mold Co., Ltd. continues to focus on innovation and customer-oriented solutions. The 48 cavity PET needle valve bottle cap mould not only meets the needs of high-speed, large-volume production but also aligns with the industry’s move toward energy conservation and environmental responsibility. By integrating precision engineering with intelligent technologies, our moulds ensure consistent quality, faster cycles, and lower production costs. This makes them highly competitive in the global packaging market. Looking ahead, we are committed to providing customized moulds that help clients achieve sustainable growth and stronger market performance.
