  The packaging industry provides protective, convenient and information-carrying solutions for various products, covering materials such as paper, plastic, metal, as well as emerging materials like seaweed.

  Driven by e-commerce, sustainability and product integrity, the supply chain has become an important part of the supply chain for food, beverages, pharmaceuticals, electronic products and industrial products.

  Key trends include eco-friendly materials, advanced protective packaging, digital tracking integration, and the adoption of artificial intelligence technology.

 

 

  Our connector inserts utilize premium polycarbonate (PC) for exceptional mechanical strength, heat resistance (125℃), and electrical insulation, with UL94 V-0 flammability for harsh environments.
  Contacts undergo precision manufacturing with 3μm silver/gold plating, ensuring optimal conductivity and durability. Rigorous testing guarantees reliability in automotive, industrial, and energy applications.

  The hood&housing are die-cast by our own molds. We have over ten types of molds. The hood&housing's material is cast aluminum alloy.

  After a series of steps such as die-casting, deburring, drilling, threading, and inspection, a complete hood&housing series is finally die-cast

  In addition to the two core components - hoods and housings, our comprehensive product range also includes essential accessories such as cable connectors, cold pressers, fixed mounting frames, professional crimping tools, needle retraction devices, and various installation components, providing complete connectivity solutions for diverse industrial applications.

PRE-INSTALLATION

  Achieve pre-installation, pre-installation of large and complex circuits Significantly improves equipment installation efficiency and reduces wiring error rates.

 

 

 

 

HIGH-INTEGRATION DENSITY

  Heavy duty connectors are engineered to provide high-density interconnection solutions that enable space-efficient system designs in industrial applications. These robust components feature modular architectures with versatile configuration capabilities, allowing for optimal spatial utilization within equipment enclosures and control panels.
  By integrating multiple contact points in compact form factors, they effectively minimize footprint requirements while maintaining reliable power and signal transmission. Their flexible combination options support customized layouts that maximize available space without compromising performance, particularly valuable in space-constrained packaging machinery where every millimeter counts. This design approach not only enhances equipment compactness but also simplifies cable management and improves overall system maintainability.

  The high protection rating (IP65, IP68) provided by heavy duty connectors offers unparalleled advantages for equipment connection systems in harsh environments. Provides effective protection in harsh environments such as sand, rain, cold, snow, ice, and oil contamination.

 

 

 

 

 
 

Packaging machinery plays an indispensable role in modern society, ranging from ensuring product safety to promoting global trade. Its influence is profound and extensive. In the fields of food and medicine, automatic packaging machines effectively isolate bacteria and oxygen through sealing, vacuum or nitrogen filling technologies (such as sterile Tetra Pak packaging for potato chips and milk), extending the shelf life. Meanwhile, blister packaging machines for medicines and automated production of infusion bags eliminate the risk of contamination and ensure safety.

Meanwhile, packaging machinery has significantly enhanced efficiency and reduced costs - beverage filling lines can handle thousands of bottles per minute, e-commerce automatic carton sealing machines can process tens of thousands of packages daily, and intelligent cutting technologies (such as carton forming machines with ±0.5mm precision) have further reduced material waste.
