What are the development characteristics of pulp molding abroad?

1. Widely used in various fields. Pulp formed products such as automotive industry, electronic products, hardware, consumer goods, medical devices, household products, and office supplies have been applied in sales packaging.

2. Use computer-aided design methods. The model of pulp molded products is designed using 3D computer software such as pro/Engineer and Solidworks. Based on the data files of the design model, rapid prototyping can be used to directly manufacture molds and product prototypes. You can also import the data files into the main cam of the manufacturing software and directly perform touch machining on the CNC machining center. At present, this technology can only be mastered by individual enterprises in China. Standardize and modularize product design. In the production of pulp molded products, mold cost is one of the important costs. Foreign manufacturers should pay attention to a wide range and good universality in the design and application of pulp molded products. For example, for general bone plates, protective angles, partitions, etc., due to the large production volume, high mold utilization rate, and simple design, the mold amortization cost is greatly reduced.

3. Advanced production equipment and reasonable process. Compared with China, its characteristics include pressure drying technology, direct hot pressing molding, no need for an oven, and a significant reduction in energy consumption. The degree of machine automation is very high, almost completely automated, saving energy and labor.

What are the problems in the development of pulp molding technology?

At the current technological level, the thickness of pulp formed products is roughly between lmm-60mm, and the thickness of general products is around 2.5mm.

2. From the current quality and application situation of pulp formed packaging products, the loading load can reach 150 kilograms, the shape is not too complex, and the inner lining packaging of products weighing less than 5 kilograms is the choice

3. The quotation for pulp forming products is generally based on the shape, structure, volume, weight, raw materials used, and manufacturing of the product_ The requirements of T art and the level of product output are currently commonly used to convert the value into unit weight (such as circle/gram or circle/ton). From the situation in the East China region, the general product quotation ranges from 9000 won per ton to 10000 won per ton. The quotation for products with high appearance and size requirements ranges from 2000 won/ton to 14000 won/ton.

The product qualification rate and the reliability of the production line in the pulp forming industrial packaging production process are major issues related to production costs. At present, the product qualification rate of domestic models is about 85% -95%.

The structure of easy to use pulp molded products. The structure and shape of pulp molded products should not cause harm to the human body, and should be suitable for human operation and handling during use.

Once again, pulp molded products, through their unique structure, undergo denaturation during loading to increase time, absorb external energy, and reduce the impact and vibration of the packaging. It is different from the shock absorber of foam packaging products. Because foam products are distributed with many compressible foam inside the material, no matter what form it is, it has good performance
