Exhibition Focus | Donghua Machinery Debuts at Qingdao Rubber and Plastic Exhibition, Medical and Multi Material Injection Molding Solutions Lead to High Popularity of Exhibitors

Qingdao, as the core gathering place of manufacturing industry in the north, has seen strong development momentum in medical packaging, daily home furnishings and other industries in Shandong and North China regions in recent years, nurturing vast market space for precision and efficient injection molding equipment. The exhibition will grandly open at the Qingdao World Expo City International Convention and Exhibition Center from July 8th to 11th.

Donghua Machinery unveiled two sets of injection molding solutionsN2-C166Booth, professional technical team stationed on-site, providing machine model explanations and process exchanges.

Two devices were continuously running at the booth, and many visitors were attracted by the injection molding process in operation and stopped in front of the machines to watch. The salesperson explains the equipment structure, molding effect, and process advantages, and communicates with customers one by one about the actual concerns on site.

　　150HD electric injection molding machine: large infusion aluminum-plastic medicine cap

The medical packaging field has almost strict requirements for production environment and product quality. As a key packaging component of infusion bottles and infusion bags, the aluminum-plastic cap for large infusion requires precise and stable coordination with aluminum rings and rubber stoppers, with multiple cavitiesmoldThe consistency of size and weight between each cavity during production directly affects the sealing performance and safety of the product.

　　

The 150HD electric injection molding machine is designed to meet the production needs of such medical products. The all electric drive mode fundamentally eliminates the potential impact of hydraulic oil on clean production environments. For products such as large infusion aluminum-plastic caps that require multi cavity precision molding, the equipment has achieved a repeated positioning accuracy of ± 0.01mm in key actions such as injection molding, mold opening and closing, and ejection. The self-locking five point elbow joint structure provides a stable mechanical foundation for multi cavity molding, ensuring that the weight and size of each cavity are consistent. Faced with the process characteristics of high-pressure injection of medical products, the high stiffness injection table mechanism controls the structural deformation within 0.05mm, effectively reducing the variable interference during the injection process and further optimizing the energy consumption in the production process.

On the first day of the exhibition, there was a good news of signing contracts on site: our company successfully completed 150HD with key customerselectric motorThe on-site delivery signing ceremony. This is not only a single product transaction, but also a direct recognition of our technical strength in the field of high-efficiency motors by the market, which has brought a good start to this exhibition.

　　130PS interlayer color mixing injection molding machine: wash cup

The production of multi material and multi color products traditionally requires multi material machines to work with specialized molds, which typically cost 2 to 3 times more than ordinary monochrome molds, and product switching is also relatively difficult. The 130PS interlayer color mixing injection molding machine provides a new path:

　　Multi color and multi material molding can be achieved using ordinary monochrome molds, and the molds do not require any modification.

　　　　

On site, the washbasin cup was used as a demonstration piece, with different materials used for the outer and core layers, and the mold used was the same as that of a regular monochrome washbasin cup mold. Sandwich injection molding injects two kinds of materials into the same the first mock examination cavity in the same injection cycle, forming a clear inner and outer layer structure. For enterprises, existing molds can directly expand the production capacity of multi-color and multi material products. The core layer can also use recycled materials according to product requirements, further reducing material costs.

　　　　

During the exhibition, the technical team of Donghua Machinery continued to provide machine model explanations and process exchanges at booth N2-C166. Welcome audience and customers to visit and explore the upgrade path of injection molding technology together.
