The customer representatives checked the various indicators of the injection mould one by one, from precise dimension measurement

The deformation, bending, and twisting of injection moulding products are mainly caused by the shrinkage rate in the flow direction of the plastic moulding being greater than that in the vertical direction, which causes the shrinkage rate of the parts to warp in different directions. In addition, due to the large internal stress that inevitably remains inside the parts during injection moulding, warping is caused. These are all manifestations of deformation caused by high-stress orientation. Therefore, fundamentally speaking, mould design determines the warping tendency of the parts. It is challenging to suppress this tendency by changing the moulding conditions. The ultimate solution to the problem must start with mould design and improvement. The following aspects mainly cause this phenomenon:     1. Mold aspect:   　　(1) The thickness and quality of the parts should be uniform.   　　(2) The design of the cooling system should make the temperature of each part of the mold cavity uniform, the pouring system should make the material flow symmetrical to avoid warping due to the flow direction, shrinkage rate is different, appropriate thickening of the difficult to mold part of the manifold, the main stream channel, as far as possible to eliminate the difference in density within the cavity, the difference in pressure, the difference in temperature.   　　(3) The transition area and corners of the thickness of the parts should be rounded enough to have good mold release, such as increasing the mold release margin, improving the polishing of the mold surface, and the ejector system should be balanced.   　　(4) Exhaust should be good.   　　(5) Increase the wall thickness of the part or increase the direction of warpage resistance, by reinforcing bars

1, Pouring system:  The gating system refers to the part of the runner before the plastic enters the cavity from the nozzle, including the main runner, the cold slug well, the runner, the gate, and the pulling needle.   2, Temperature control system: The temperature adjustment system meets the requirements of the injection process for the mould temperature, and a temperature adjustment system is required to schedule the mould temperature. Regarding injection molds for thermoplastics, the main thing is to design a cooling system to cool the mold (it can also be heated). The common method of mold cooling is to open a cooling water channel in the mold and use the circulating cooling water to take away the heat of the mold. In addition to using cooling water to pass hot water or hot oil, the heating of the mold can also install electric heating elements in and around the mould.   3, Forming part system: The forming part system refers to the combination of various parts that constitute the shape of the product, including movable mold cores, movable mold inserts, fixed mold cores, fixed mold inserts, etc. Under normal conditions of fixed mold, the outer surface of molded products, and under normal conditions of movable mold, the inner and outer surfaces of molded products. The fixed and movable mold cores are combined to form a cavity, and then the post-injection system will flow the plastic into the cavity. After cooling, the fixed and movable mold cores are opened, which is the required product.   4, Organization system: The organization system refers to the fact that the inversion of the product is inconsistent with the normal demolding direction, and it is necessary to do organization core pulling to meet the normal demoulding of t

1. Process analysis of plastic products   Before designing the mold, the designer should fully analyze and study whether the plastic product conforms to the principle of injection molding processing, and need to carefully negotiate with the designer of the product to reach a consensus. This includes necessary discussions on the geometric shape, dimensional accuracy and appearance requirements of the product, and trying to avoid unnecessary complexity in mold manufacturing.   2. Mold structure design.   A high-quality mold not only requires good processing equipment and skilled mold manufacturing workers but also a very important factor is good mold design. Especially for complex molds, the quality of mold design accounts for more than 80% of the mold quality. An excellent mold design is: under the premise of meeting the customer's requirements, the processing cost is low, the processing difficulty is small, and the processing time is short.   3. Determine the mold material and select standard parts   When selecting mold materials, in addition to considering the accuracy and quality of the product, the actual processing and heat treatment capabilities of the mold factory should be considered to make the right choice. In addition, to shorten the manufacturing cycle, existing standard parts should be used as much as possible.   4. Parts processing and mold assembly.   In addition to giving the best structure and reasonable tolerance matching during design, the accuracy of the mold, parts processing and mold assembly is crucial. Therefore, the choice of processing accuracy and processing methods occupies a dominant position in mold manufacturing.  

The production of the Blood Testing Case Parts Medical Plastic Molds involved several significant challenges: 1. High Precision Requirements: The Medical Molds needed to produce parts with extremely high precision to ensure the blood testing device functions correctly and provides accurate results. This required meticulous design and manufacturing processes to maintain tight tolerances. 2. Complex Geometry: The blood testing case parts have intricate designs with multiple cavities and intricate features. Creating a mold that could accurately replicate these complex geometries required advanced CAD/CAM software and precise machining techniques. 3. Material Compatibility: Selecting appropriate materials for both the mold and the injected parts was essential. The materials had to be biocompatible, durable, and capable of withstanding sterilization processes without degrading. 4. Surface Finish: The parts needed to have a smooth and consistent surface finish to ensure proper functionality and ease of cleaning. Achieving this required careful attention to the mold pol

The Specialty of The CNC Processing Workshop Equipment Operation and Maintenance: CNC operators need to skillfully operate computer CNC machine tools, such as milling machine, lathe, drilling machine, etc. They need to set the machine tool parameters and cutting tools correctly according to the work instructions, and check the normal operation of the equipment. In addition, daily equipment maintenance and maintenance are also their responsibilities, including c

The injection molding process of plastic parts mainly includes four stages: filling - holding pressure - cooling - demolding. These four stages directly determine the moulding quality of the product, and these four stages are a complete continuous process. 1. Filling stage The filling is the first step in the entire injection molding cycle. The time starts from the time the mould is closed and the injection is started until the mould cavity is filled to about 95%. In theory, the shorter the filling time, the higher the moulding efficiency, but in practice, the moulding time or injection speed is subject to many conditions. 2. Holding pressure stage The function of the holding pressure stage is to continuously apply pressure, compact the melt, increase the density of the plastic (densification), and compensate for the shrinkage of the plastic. During the holding pressure process, the back pressure is high because the mold cavity is already filled with plastic. During the holding pressure compaction process, the screw of the injection molding machine can only move forward slowly and slightly, and the flow speed of the plastic is also relatively slow. The flow at this time is called holding pressure flow. 3. Cooling stage In injection molding, the design of the cooling system is very important. This is because only when the molded plastic products are cooled and solidified to a certain rigidity can they avoid deformation due to external forces after demolding. Since the cooling time accounts f

As a plastic mold manufacturing company, using PP material to injection mold cosmetic bottle caps can present several challenges: 1. Dimensional Accuracy and Precision - Shrinkage Control: PP has a relatively high shrinkage rate, which can lead to dimensional inaccuracies. Ensuring precise control over the shrinkage is critical to achieving the correct cap dimensions. - Tight Tolerances: Cosmetic bottle caps require tight tolerances to ensure proper fit and function with the bottle. Achieving these tolerances consistently can be challenging due to PP's shrinkage and warpage. 2. Surface Finish and Aesthetics - Surface Defects: PP is prone to flow marks, weld lines, and sink marks, which can affect the appearance of the caps. Cosmetic products demand high-quality finishes, so minimizing these defects is essential. - Color Consistency: Maintaining uniform color across production batches can be difficult due to variations in material and processing conditions. 3. Mold Design Complexity - Gate Location and Design: Proper gate placement is crucial to ensure uniform material flow and minimize defects. Inadequate gating can lead to uneven filling, weld lines, and visible marks on the caps.

A hot mold surface keeps the plastic surface liquid long enough to build pressure in the cavity. If the cavity is filled and the cavity pressure can press the soft plastic against the metal before the frozen skin hardens, the cavity surface replication is high. On the other hand, if the plastic entering the cavity under low pressure pauses, no matter how short, its slight contact with the metal will cause stains, sometimes called gate stains.   For every plastic and plastic part, there is a mold surface temperature limit beyond which one or more adverse effects may occur (for example, the component may flash). Higher mold temperatures mean less resistance to flow. On many injection moulding machines, this naturally means faster flow through the runners, gates, and cavities, and because the injection mould flow control valves used do not correct for this change, faster filling will cause higher effective pressures in the runners and cavities. Flash may be caused. Because the hotter model does not freeze the plastic that enters the flash area before high pressure is formed, the melt can flash around the ejector pin and overflow into the parting line gap. This indicates that good injection rate control is required, and some modern flow control programmers can indeed do this.   Generally, an increase in mold temperature will reduce the condensation layer of plastic in the cavity, making it easier for the molten material to flow in the cavity, resulting in larger part weight and better surface quality. At the same time, an increase in mold temperature will also increase the tensile strength of the part. Many plastic injection moulds, especially engineering thermoplastics, operate at relatively high temperatures. If the mold is not insulated, the heat lost to the air and the injection molding machine can easily be as much as the loss of the shot cylinder. So insulate the mold from the machine plate and, if possibl

Definition of Injection Mould   The mold used in plastic injection moulding is called an injection mould, or injection mold for short. Injection moulds can mold plastic products with complex shapes, and precise dimensions or with inserts in one go.   For injection moulding processing, molds and injection molding machines have a great impact on the quality of molded products. It can even be said that the mold plays a greater role than the injection molding machine. If you do not fully understand the mold during injection molding, it will be difficult to obtain Excellent molded products.   Structure of Injection Mould   The structure of the injection mold is determined by the type of injection molding machine and the structural characteristics of the plastic part. Each mold is composed of a movable mold and a fixed mold. The movable mold is installed on the moving plate of the injection molding machine, while the fixed mold is installed on the fixed plate of the injection molding machine; during injection molding, the movable mold and the fixed mold are closed to form a pouring system and cavity. When the molds are separated, the plastic parts or beer The parts are left on the side of the movable mold, and then the ejection mechanism installed in the movable mold is used to eject the plastic parts. According to the different functions of each component in the mold, a set of injection molds can be divided into the following parts:   1. Molded parts   Parts that give shape, structure, and size to molded materials are usually composed of a core (punch), a concave mold cavity, a threaded core, and an insert.   2. Gating system   It is a channel that gui

The injection mould is composed of several steel plates and various parts. It is basically divided into: A. Molding device B. Positioning device C. Fixtures D. Cooling system E. Constant temperature system F. Flow channel system G. Ejection system According to the different types of pouring systems, plastic injection moulds can be divided into three categories: 1. Edge gate mold: The runners and gates are on the parting line and are demoulded together with the product when opening the mold. The design is simple, easy to process, and the cost is low, so more people use the edge gate system for operations. 2. Pin-point gate mold: The runner and gate are not on the parting line, usually directly on the product, so it is necessary to design an additional set of pin-point parting lines. The design is more complex and the processing is more difficult. Generally, the pin-point gate mold should be selected according to the product requirements. 3. Hot runner mold: The structure of this type of plastic mould is roughly the same as that of pin-point gate mold. The biggest difference is that the runner is located in one or more hot runner plates
