2. Working Principle and Complete Molding Process of 100L Extrusion Blow Molding Machine
2.1 Basic Working Principle of Extrusion Blow Molding
The working principle of the 100L extrusion blow molding machine follows the classic extrusion blow molding process logic, which is divided into four core stages: plastic extrusion plasticization, parison molding, mold clamping inflation and cooling demolding. Firstly, the plastic raw materials specially used for chemical tanks are heated and plasticized uniformly through the extrusion system to form a molten plastic melt. Then, the melt is extruded downward through the die head to form a hollow cylindrical plastic parison matching the size of the 100L storage tank.
After the parison reaches the preset length, the hydraulic clamping system quickly closes the mold to clamp the parison, and the blow needle penetrates into the hollow parison for high-pressure inflation. The inflated plastic parison is closely attached to the inner wall of the mold, and the product shape is formed under the action of air pressure. Finally, through circulating water cooling and air cooling system, the product is rapidly cooled and shaped, and the mold is opened for automatic demolding to complete the whole production cycle of 100L chemical storage tank.
Different from small blow molding equipment, APOLLO 100L extrusion blow molding machine optimizes the inflation pressure and cooling cycle parameters for the large-volume and thick-wall characteristics of 100L industrial tanks, avoiding incomplete shaping, internal stress residue and tank body deformation problems that are easy to occur in large hollow product molding, ensuring the dimensional accuracy and structural stability of finished chemical storage tanks.
2.2 Complete Production Process of 100L Chemical Storage Tank
The standardized production process of 100L chemical storage tank based on APOLLO extrusion blow molding machine includes raw material pretreatment, automatic feeding, extrusion plasticization, parison extrusion, mold clamping, high-pressure blowing, constant temperature cooling, mold opening demolding and post-processing inspection. Each link is precisely matched to ensure product qualification rate and production efficiency.
In the raw material pretreatment stage, high-density polyethylene raw materials and chemical-resistant modified additives are dried and screened to remove impurities and moisture, preventing bubble defects and performance attenuation of finished tanks. The automatic feeding system quantitatively transports raw materials to the extrusion barrel, and the multi-stage temperature control system heats and plasticizes the raw materials in sections to ensure uniform melt viscosity and stable plasticization effect.
In the parison extrusion stage, the intelligent wall thickness control system dynamically adjusts the extrusion speed and die gap according to the tank structure characteristics, realizing thick-wall reinforcement at the bottom and mouth of the tank and uniform wall thickness of the tank body, which improves the pressure resistance and drop resistance of the chemical storage tank. After mold clamping and inflation, the constant-temperature circulating cooling system fully cools the product to eliminate internal stress, and the finished product is automatically demolded and sent to the inspection link for size detection, air tightness test and appearance inspection.
2.3 Key Process Parameter Settings for Industrial Chemical Tanks
The production of industrial 100L chemical storage tanks has strict parameter standards, which are completely different from ordinary civil plastic barrels. The extrusion temperature of the APOLLO 100L extrusion blow molding machine is stably controlled between 180℃ and 220℃ according to the characteristics of chemical-resistant plastic raw materials, ensuring full plasticization of raw materials without thermal decomposition. The parison extrusion speed is set in stages to avoid parison sagging and uneven wall thickness caused by excessive gravity of large-volume parison.
The mold clamping pressure is maintained at 12-15MPa to ensure tight mold closing and no flash on the product edge. The blowing pressure is controlled at 0.6-0.8MPa, which can fully stretch the plastic parison to fit the mold without causing excessive tension and thinning of the tank wall. The cooling cycle time is reasonably matched according to the tank wall thickness, ensuring complete shaping of the product while maximizing production efficiency, and the daily stable output of qualified 100L chemical tanks can reach more than 300 pieces.
