Logistics Packaging Injection Mold Production Process
——
1.Multi-cavity injection molding technology
Logistics packaging injection mold to achieve multi-cavity injection molding technology, “one mold, multi-cavity” design (such as a mold 8 cavities or 128 cavities), a single injection output of a number of logistics packaging products, the efficiency can be up to the traditional single-cavity molds 5-8 times, to reduce the occupancy of equipment and waste (such as the use of hot runner system), the cost per unit of product reduction of more than 30%. H-type or radial runner layout is adopted in the design of the injection mold to ensure that the melt reaches all cavities at the same time and the pressure is uniform. The diameter of the main runner decreases step by step, and the cold material well is set at the end to avoid uneven filling.
2. Gas Assisted Injection Molding Technology (GAIM)
Logistics packaging injection mold to meet the gas-assisted molding technology, in the thick-walled area of the logistics packaging products injected with nitrogen to form a hollow structure, weight reduction of 20% -40%, while enhancing the rigidity of the gas to maintain pressure to compensate for plastic shrinkage, reduce surface defects. The design of the injection mold is 2-3 times of the wall thickness of the cross-section of the gas channel, the corner of the arc transition, combined with the reinforcement as a sub-gas channel to enhance the efficiency of the shrinkage compensation, the use of high-temperature sealing ring, the gas needle gap <0.02mm, to prevent backflow of molten material.
Specify the type of plastic (e.g. PP, ABS) and post-processing requirements (e.g. spraying, silk-screen printing), and provide 2D or 3D plastic part drawings should be provided. At the same time, provide the production volume, appearance requirements, tolerance standards, etc.
Generally speaking, our engineers will start to prepare the quotation immediately after the customer provides the complete production requirements. Usually it takes about 1-3 days.
The lead time for regular injection molds is usually 30-60 days, and may be longer for complex molds. For example, the typical lead time for liquid silicone molds is around 60 days, covering design, manufacturing, mold testing, etc.
High-precision processing technology: High-precision equipment such as CNC machining centers (CNC) and electric discharge machining (EDM) are used to optimize the design process in combination with CAD/CAM software. Quality control: Inspection of key dimensions of the mold by Coordinate Measuring Machine (CMM) and verification of multiple sample batches during the trial molding stage. Material Selection: Use die steel with high wear resistance (e.g. H13, S136) and surface treatment (e.g. nitriding, chrome plating) for die nuts to extend the life.
After every 50,000 molds, check the guide pillar, ejector pin and other wear parts, and clean up the residual plastic and rust on the mold surface. Use high temperature grease for sliding parts (e.g. tilt top, slider) to reduce friction loss. Ensure that the water circuit is smooth and the temperature difference is ≤5℃ to avoid cracking of the mold due to thermal stress.
Mould cost of materials accounted for about 30-40% (such as 1 ton of P20 steel price of about 20,000 yuan), processing costs accounted for more than 50% (CNC labor hourly rate of about 80-150 yuan / hour). Small batch production can choose aluminum mold or simplify the structural design; more than 100,000 pieces is recommended to use carbide inserts to enhance life!
Mould injection products need to fully meet the design requirements (such as size, appearance), and can be continuous and stable production. Mold marking, inspection reports (such as material hardness test) and engineering drawings should be complete.
Mould steel (such as S136H, NAK80 and other imported materials cost more) and the type of mold embryo (aluminum mold short-term cost is low but short life) directly affect the cost, the use of CAD/CAE/CAM design technology, hot runner system, etc. will increase the upfront investment, but can enhance the long-term benefits (such as reducing the sprues, increase production capacity).
