Common injection molded products include transparent covers, lampshades, instrument panel housings, protective screens, etc.
Manufacturing Process Of Agricultural Machinery Injection Mold
——
Understand the function, size, and tolerance requirements of agricultural machinery parts, determine the plastic material, evaluate the production lot of the part, and decide the service life of the mold before manufacturing the injection mold.
SolidWorks Front CAD design software is used to design the injection mold model according to the customer's needs, and Moldflow and other software are used to simulate the flow path.
The mold steel is made of raw materials such as P20, H13, S136, etc., and the mold cavities are rough machined with CNC milling machine to ensure the basic shape, and at the same time, the EDM, wire cutting, heat treatment and finishing are carried out. Manufacturing process.
After the completion of the agricultural machinery injection mold manufacturing in the factory assembly test mold quality testing process, assembly of moving mold, fixed mold, slider, ejector and other parts, in the injection molding machine for the quality of molding and the fit of the quality testing
FAQ:
1. How to ensure the dimensional accuracy of the mold and product consistency?
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.
2. Molds are easy to wear or short life, how to improve?
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.
3. Why is the cost of mold opening higher?
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!
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.

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).
