Energy consumption: plastic absorption is thermal processing, and the energy consumption is relatively large compared with other industries, accounting for about 8% of the product material cost. Labor: Plastic suction is mainly produced by machines, with less labor, accounting for about 65,438+00% of the product material cost.
Transportation: depending on the customer's distance from the factory, profit: the net profit of plastic factory is generally very low, 12%-20%, depending on the payment term, 30 days settlement 14% material cost: the calculation of product material cost is complicated.
Raw material price: according to the use of the product, determine what kind of material to use, what grade of material to find the lowest supplier's film thickness: predict how thick the product should be made into a film, and the number of typesetting should be determined according to the thickness and shape of each molded part; According to the overall size and shape of the product, how many molds can be arranged in a version, which will reduce the quality of the product and increase the material loss.
The material loss rate that makes the cost rise: The main factor is the matching degree between the product shape, product quantity and external dimension and the chassis of the plastic suction machine. The more square the shape, the greater the output and the smaller the loss rate.
Put the plastic product flat on your hand, measure the unfolded size and weigh it. Calculate the thickness of the material according to the size and weight. In centimeters, the calculation formula is: length x width x density x thickness x unit price of raw materials x2 = unit price of finished products.
For example, a PVC product with a folded foam shell has an unfolded size of 30X 10cm and a gram weight of 25g. The calculated material thickness is 0.6mm, and its unit price is 30x10x1.4x0.0125x2 = 0.63 yuan.
