What are the main process requirements of polyurethane foaming machine?

2022-08-05

Fuleite polyurethane high-pressure foaming machine has strict requirements for the treatment of the production process and the control of the production process. The changes in the mechanical control during production, the raw materials, molds, preheating temperature and curing time of the selected products directly affect the molding of the product process. The control points of foaming process are mainly described here:

1. The combination of polyisocyanate, polyether, foaming agent in black and white materials, the chemical properties of catalyst and foam stabilizer directly determine the chemical reaction of polyurethane synthesis equipment and the physical properties of foam. If you need to buy, you must choose a well-known foaming material enterprise, which is a qualified polymer.

2. Polyurethane high-pressure foaming machine strictly controls the proportion of stock solution and injection volume, and controls the proportion of black material, polyether and cyclopentane. When the total injection volume remains unchanged, bubbles will appear if the proportion of black material is too high, soft bubbles will appear if the proportion of white material is too high, and bubbles will appear if the proportion of cyclopentane in polyurethane high-pressure foaming machine is too low. The non-uniform proportion of white material will lead to the non-uniform mixture, which will lead to the shrinkage of foam.

Guangdong Fuleite Electromechanical Technology Co., Ltd,It is a polyurethane machinery automation production enterprise integrating R & D, production, sales and after-sales service. Our company develops and manufactures various polyurethane pouring machines, polyurethane foaming machines, automatic foaming production lines (suspension line / ground rail line / disk line, etc.), automatic foaming mold and mold base, mechanical arm and other complete sets of polyurethane foaming equipment, helping thousands of polyurethane product production-oriented enterprise users achieve "high product excellence rate and low equipment failure rate".
