Applications Scenarios
Product Description
JWELL Barrier Mixing Blow Molding Screw is developed for the extrusion stage of hollow blow molding production. Different blow-molded products can require different screw configurations, so this series adopts application-oriented designs rather than using one general structure for every product.
The documented screw design combines a barrier section with a mixing structure. This combination is intended to support stable screw extrusion and the plasticizing effect required for hollow blow molding. The appropriate configuration should be selected according to the processed material, product shape and blow molding equipment.
The series covers a wide range of hollow containers. Applications listed in the source document include engine-oil cans, lubricant containers and coolant tanks in different specifications. Industrial packaging applications include stackable drums and chemical packaging barrels, while larger hollow products include blow-molded pallets.
Automotive applications include seats, vehicle toolboxes, air ducts, guide plates or deflectors, bumpers and rear spoilers. The screw series can also be applied to special-shaped pipe fittings and other irregular hollow blow-molded products.
Because these products differ significantly in size, shape and processing requirements, screw selection should begin with the actual finished product and resin. The barrier and mixing structure should then be matched to the extrusion and plasticizing requirements of the application.
Across the series, the common design principle remains the combination of barrier and mixing functions. The detailed screw geometry, however, should be evaluated against the specific hollow product instead of being treated as a universal configuration.
For quotation and technical evaluation, customers should provide the polymer, finished-product description, blow molding machine model and required operating conditions. Screw diameter, effective length, L/D ratio, rotational speed and output requirements should also be confirmed because these numerical specifications and material grades are not included in the source document.
