Research on production cost of free-trimming pulp molding products
Abstract: In order to systematically study and analyze the production cost of free-trimming pulp molding products, the research group studied the impact of the production die design, die heating system design and die maintenance on the production cost. Based on the manufacturing method of free-trimming pulp molding mold according to the theory of thermal expansion, compare the structural requirements of free-trimming pulp molding mold in production practice, and the overall design requirements of free-trimming pulp die products are summarized. The production cost is comprehensively calculated and analyzed from the output, energy cost, mold cost, maintenance cost, product quality and qualified rate.
The analysis results show that: under the condition of mold mounting surface of the same size, the production of free-trimmingpulp molding products is significantly lower than margin trimming products, the mold cost and maintenance cost of free-trimming products is far higher than that of automatic margin trimming products, and the waste rate of free-trimmingproducts is higher. The waste rate of free-trimming products is high. Therefore, no matter from the analysis of output, quality, cost, mold interchangeability and other aspects, pulp mold free-trimming products are obviously not advantageous, and there are major production problems unforeseen by the initial entrants.
