A better tooling maker in China

  FAQ: How long do tools take? This is one of the questions we get asked the most, however, there are so many variables in tool manufacturing that no one rule can be applied. In some cases, we have moulded trial 1 sample parts within 10 working days. In other cases, it has taken 10+ weeks. It can often vary on the volume of work in the tool room, along with the complexity of the tool. Got any other questions for us?

 A set of high-quality molds not only requires good processing equipment and skilled mold manufacturing workers, but also another very important factor is to have a 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. To achieve this, it is necessary not only to fully digest the customer's requirements, but also to understand the injection molding machine, mold structure, processing technology and the mold factory's own processing capabilities. Therefore, to improve the level of mold design, the following points should be achieved: 1. Understand every detail in each set of mold design and understand the purpose of each part in the mold. 2. Refer to previous similar designs when designing, and understand the situation during...

 1. Injection mold custom processing workpiece to plane positioning According to the number of degrees of freedom restricted by the plane, it can be divided into three types: The main support surface restricts the positioning plane of the three degrees of freedom of the workpiece, and is often used for the positioning surface of the workpiece with relatively high precision. The guide support surface is a positioning plane that limits the two degrees of freedom of the workpiece, and is often made into a narrow and long surface. The thrust support surface is a plane that limits one degree of freedom. In order to ensure accurate positioning, the area of the plane is often made as small as possible. 2. Injection mold custom processing workpiece is positioned with a round hole Long pins limit 4 degrees of freedom; short pins limit 2 degrees of freedom. 3. Injection mold custom processing workpiece outside cylindrical surface positioning The positioning datum is the centerline of the out...

 The design of the ejection mechanism of the injection mold. The ejection mechanism of the injection molded part is a very important mechanism in the injection mold. The structural form of the ejection mechanism of the injection molded part needs to be determined according to the shape, size, wall thickness, precision and six elements of the injection molded part. . Since the ejection mechanism of injection molded parts is installed on one side of the movable template of the injection machine, under the premise that the cavity of the fixed mold has been opened and the core pulling of the injection molded parts has been completed, its function is to eject the molded chilled hard injection molded parts out of the mold cavity or core. Due to the thermal expansion and contraction of the injection molded parts, the cold and hard injection molded parts will be tightly wrapped on the cores of the movable and fixed molds. Generally, it is required to keep the injection molded parts in the ...

 1. Screw speed The screw speed in injection molding conditions refers to the speed of the screw used to mix the pellets. The unit is rpm (rev/minute). If the screw speed is too fast, air may be mixed into the molten resin and gas may be easily generated. If the screw speed is too slow, there may be insufficient mixing and deviations in material quality may occur. 2. Screw back pressure Screw back pressure refers to the pressure when the screw is retracted during material metering. The unit is MPa or kgf/cm2. The mixing state of the material will change due to the change of back pressure. 3. Mold opening and closing speed Mold opening and closing speed refers to the mold opening speed and mold closing speed of the mold, the unit is mm/s. Shorter mold opening and closing times are effective in shortening cycle time, but if the mold closing speed is too fast, the risk of violent collision of the mold will increase, so the brake must be applied just before the mold closing is complete...

 1. Design reference for inclined top lateral core-pulling mechanism of injection mold: 1. Conventional form of lateral core mechanism: slider + inclined guide column, slider + hydraulic cylinder, inclined top block, inclined push block, inclined slider + spring, etc. 2. The length of the guide section of the ram is at least 2/3 of the length of the ram. 3. The ejection angle of the inclined roof should be designed within 6~12゜ as far as possible, and the minimum angle should not be less than 3゜. 4. When the product structure can only reach 20° when the product structure is limited, it is necessary to use a double-link inclined roof mechanism. 5. If the inclined ejector pin is purchased, the minimum Ф16MM is used, and the conventional use is Ф20MM. For large injection molds, the inclined ejector pin is preferably used Ф25MM. 6. It is necessary to design the auxiliary reference plane for the inclined jack head with the aid of the ejector rod. 7. The inclined jacking block and the in...
