Plastic drum manufacturing process
As a common container in daily life, plastic buckets are widely used in chemical, food, medicine and other fields. Its manufacturing process involves a number of links,
the following will introduce the whole process of plastic drum manufacturing in detail.
First, material preparation
Raw material selection: According to the use and performance requirements of plastic drums, choose the appropriate plastic raw materials, such as polyethylene (PE),
polypropylene (PP), polyester (PET), etc.
Raw material inspection: Quality inspection of the selected raw materials to ensure that they meet the production requirements, no impurities, no pollution.
Storage of raw materials: Store qualified raw materials in a special warehouse, pay attention to moisture, fire and sun protection.
Two, design mold
Determine the specifications: according to customer needs or market standards, determine the size of plastic drums.
Drawing drawings: Using CAD and other software to draw three-dimensional drawings of plastic drums, and design the mold structure.
Mold review: Organize experts to review the designed mold drawings to ensure that the mold structure is reasonable and feasible.
Third, mold production
Material purchase: According to the mold drawing, purchase the required mold materials, such as steel, alloy, etc.
Machining: The use of milling machines, drilling machines and other mechanical processing equipment to cut and drill the mold material to form the preliminary shape of the mold.
Heat treatment: Heat treatment of the processed mold, such as quenching, tempering, etc., to improve the hardness and wear resistance of the mold.
Assembly and debugging: Assemble the machined mold parts together, and debug to ensure that the mold can be used normally.
Fourth, plastic melting
Heating equipment: Use special heating equipment, such as injection molding machine heating barrel, to heat plastic raw materials.
Melting process: the raw material is added to the heating equipment, through heating and stirring, so that it reaches a molten state.
Temperature control: strictly control the melting temperature to ensure that the plastic raw materials are melted in the best state.
Five, injection molding
Mold installation: Install the adjusted mold on the injection molding machine.
Injection molding operation: the molten plastic raw material is injected into the mold and cooled and cured in the mold.
Release parts: After the plastic drum is cooled and cured, the finished product is removed from the mold.
Post-processing
Deburring: Deburring the injection molded plastic drum to ensure that its surface is smooth and flawless.
Sanding: Polish the edges and joints of the plastic drum to make it smoother.
Cleaning: Clean the plastic drum with a special cleaning agent to remove the oil and impurities on the surface.
Seven, quality testing
Appearance inspection: Check the appearance of the cleaned plastic drum to ensure that it has no scratches and stains.
Size measurement: Use measuring tools to measure the size of the plastic drum to ensure that it meets the design requirements.
Performance test: Perform performance tests such as tightness and pressure resistance on plastic drums to ensure that their quality is up to standard.
Viii. Packaging and shipment
Packaging: The qualified plastic drums will be packaged, generally using cartons or wooden cases.
Labeling: Label the product name, specifications, quantity and other information on the package, and paste anti-counterfeiting labels.
Delivery: The packaged plastic drums will be delivered according to customer demand.
The above is the whole process of plastic drum manufacturing, through strict process flow and quality control, to ensure that the quality of the produced plastic drum is stable and reliable.
