1. The cavity and core of plastic injection molds have three-dimensional surfaces
The external and internal shapes of plastic injection molds are directly formed by the cavity and core. These complex three-dimensional surfaces are difficult to machine, especially the blind hole type inner forming surface of the cavity. If traditional machining methods are used, it not only requires high level of workers' skills, but also many auxiliary tools and cutting tools, and the machining cycle is long.
2. Injection molding molds specialize in division of labor and dynamic combination
As the production batch of molds is small, they generally belong to single-piece production. However, molds require many standard parts, from large mold frames to small ejector pins. It is impossible for these parts to be completed by a single manufacturer alone, and the manufacturing process is complex, with uneven use of ordinary equipment and CNC equipment.
3. Injection molding molds require high precision and surface quality, and long service life
The dimensional accuracy of the plastic parts is generally required to be IT6-7, and the surface roughness is Ra0.2-0.1μm. The corresponding dimensional accuracy of the plastic injection mold parts needs to reach IT5-6, and the surface roughness needs to be below Ra0.1μm. The roughness of the laser disc recording surface needs to reach the level of mirror processing at 0.02-0.01μm, which requires the surface roughness of the mold to reach below 0.01μm. Long-life injection molds are necessary to improve efficiency and reduce costs. Currently, the service life of injection molds is generally required to be more than one million times. Precise injection molds require a high stiffness mold frame, increased template thickness, and increased support columns or conical positioning elements to prevent deformation of the mold under pressure, which can sometimes reach 100MPa. The ejector device is an important factor affecting product deformation and dimensional accuracy, so the optimal ejector point should be selected to ensure uniform mold release. High-precision injection molds mostly use inlaid or full-fit structures in their structure, which requires a significant improvement in the machining accuracy and interchangeability of mold parts.
4. Injection molds designed and manufactured in different locations
Mold manufacturing is not the end goal, but rather, mold manufacturers design and manufacture molds based on the customer's final product design requirements. In most cases, plastic injection molding production of the product is also done by other manufacturers. This creates a situation where product design, mold design and manufacturing, and product production are carried out in different locations.
5. The process flow of plastic injection molds is long, and the manufacturing time is tight
For injection molded parts, most of them are matched with other components to form a complete product. In many cases, they are waiting eagerly for the injection molded parts to be ready when other parts have already been completed. Because of the high requirements for the shape or dimensional accuracy of the product, and the fact that resin materials have different properties, after the injection mold is completed, it needs to be repeatedly tested and corrected, making the development and delivery time very tight.
Key Points Of Mould Making
Automotive bumper injection mold is an important tool in the manufacturing of car bumpers. The mold is designed to create a specific shape and size of the bumper that fits the specific make and model of the car. To create a high-quality bumper injection mold, there are several key points that you need to consider.
Firstly, you need to pay attention to the design of the mold. The mold design should be precise, efficient, and able to withstand the pressure of the injection process. You need to ensure that the mold is designed with the correct geometries that will allow for a strong and durable bumper.
Secondly, you need high-quality materials to make the mold. The materials used should be able to withstand the heat and pressure of the injection molding process to ensure a perfect finished product. The materials must also be long-lasting and able to withstand a lot of wear and tear.
Thirdly, you need experienced professionals to handle the mold-making process. You need experts who are highly skilled in the process of creating injection molds for automotive parts in general, and bumper molds, in particular. This ensures that the mold is designed, produced and finished with a high level of precision, fit, and function.
Finally, you need to have close supervision and quality control during the manufacturing process. This ensures that there are no defects or issues with the finished product. In this way, your company will be able to meet the high demands and expectations of the automotive industry and your customers.
In summary, making a automotive bumper injection mold requires attention to detail, high-quality materials, experienced professionals and close supervision. With these key points considered, your company can create a top-quality mold, ensuring strong and durable bumpers that meet the exacting standards of the automotive industry.
