Custom Plastic Injection Mold Manufacturing Service In China
The Injection Mold Overview
According to customer requirements, this steel mould needs to be manufactured in accordance with HASCO standards. Therefore, even if we design the thread at the water inlet and outlet, we will follow the BSF pipe thread PT1/4. If in the future, during the mass injection molding production process in the customer’s factory, their operators injure the mold thimble or some accessories during injection molding, the customer can easily purchase HASCO standard mold parts locally for replacement and repair. Customers from the United States and Brazil are different, and they require DME standards. Therefore, the export mold manufacturing standard is an important indicator for us in the mold evaluation stage.
According to the requirements, the mold base adopts conventional C45 mold steel, and the mold core material chooses NAK80. NAK80 steel has good machinability, polishing and etching properties. It has been pre-hardened to 285-330HB (30-36HRC) before leaving the factory. It has the characteristics of good processing dimensional stability, no need for heat treatment, and the mold life is generally up to 500,000 times, so we often use this steel to make thermoplastic injection molds.
Review the mold design and mold engineering
The first difficulty: The visible edge of the heat dissipation window cannot leave a parting surface.
The second difficulty: the design of the injection point gates.
The third difficulty: control the joint line and air mark of the product appearance.

Sample delivery and export mold
At this point, we can arrange custom-made fumigation-free wooden boxes and pack the mould for shipment. There is no need for customers to worry about the transportation. We will arrange for international freight companies to deliver the moulds to the customer’s factory safely and on time. It is ok if the customer has their own agent, we can send the packaged wooden box with the mould to their warehouse.
The Influence of Injection Mold on Mass Injection Production
The injection mold starts from the design, and the rationality of the mould design will have a decisive impact on whether the mass production of injection moulding will be smooth in the future. Whether the mould design is reasonable or not, it requires us to use mould flow analysis software to simulate the plastic filling process and generate a series of parameters to judge.
Another is the impact of mold manufacturing and processing tolerances for injection molding. Our CNC centre will be well maintained every week to ensure machining accuracy. The processing of EDM is also divided into rough work and fine work to ensure that the final size meets the requirements. Two-dimensional and three-dimensional testing instruments are used at any time to detect various processing steps in the mould manufacturing process.
The final decision on whether the quality of the injection mold is OK or not is the mold test. Fix the injection mold on the injection molding machine, and then adjust the injection molding temperature, pressure, time and other parameters to obtain perfect injection molding parts step by step. Getting a good sample means that the set of molds has passed half the test. The other half of the test is the next small batch trial production. Keeping the injection molding parameters unchanged, the mold can run stably for 50 shots or even 100 shots, and the quality of the obtained plastic products is consistent with the tested samples, so we can say that this set of molds has completely passed the test.
