Cycle time: Injection molding is a comprehensive process, which is related to the time of each procedure. So it directly affects the thermal history and time of the force acting on the polymer solids melt. And the product and affects the product quality and production efficiency. In the molding cycle, the main part is the injection holding time, cooling time, mold opening time, and demolding time. A complete cycle is composed of closing the door-closing the mold-injection holding pressure-screw measurement-cooling-opening the mold-ejecting the product-opening the door to take the parts (there is no option for fully automatic). The molding cycle directly affects labor productivity and equipment utilization. Therefore, in the production process, the relevant time in the molding cycle should be shortened as much as possible under the premise of ensuring quality. In the entire molding cycle, the injection time and cooling time are the most important, they all have a decisive impact on the quality of the product. The filling time in the injection time is directly inversely proportional to the filling rate, and the filling time in production is generally about 3-5 seconds. The holding pressure time in the injection time is the pressure time for the plastic in the cavity. This accounts for a large proportion of the entire injection time, generally about 20-120 seconds (extra-thick parts can be as high as 5-10 minutes).

Traditional machining process Traditional processing technology is a processing technology that people produce based on experience in the process of continuous research. For traditional processing technology, most of the materials used are derived from natural resources in real life, integrating measurement and processing steps, and finally forming traditional machining technology. In mechanical manufacturing, traditional machining processes are mostly used, but this process requires high professional quality of operators, which leads to certain uncertainty in traditional machining processes. CNC machining process Numerical control processing technology is based on traditional machining technology, using machine tools for processing. For CNC machining, the work content is more complicated, and the technology involved includes not only traditional crafts, but also computer technology. By programming it and adopting the corresponding control program, the accuracy and quality of the parts can be better guaranteed. Compared with the traditional machining process, more complex process parts can be produced.

WHAT ARE YOU MOLDING? The first thing I take into consideration is the material being molded. With abrasive, glass-filled materials, my focus would be on addressing concerns over wear and erosion unless the expected volume is extremely low. But with the most common glass-filled materials, cooling is more critical than with other materials, and the best steels to address wear have lower thermal conductivity. Carbide inserts are the exception; they have excellent wear properties along with great thermal conductivity, but the costs and lead times to replace these need to be considered. With corrosive materials such as PVC, stainless steel is a common choice. Using cheaper options will require critical procedures to prevent corrosion. On parts that have very high surface-finish expectations, tool steels that have lens-grade specs should be considered. For molding materials that do not contain abrasives like glass fibers or corrosive ingredients, P-20 steel is the most common choice. But with smaller tools for high-volume production, hardened tool steels are always a good option to prolong the tool life with reduced maintenance. On the other hand, aluminum can be an excellent choice for lower-volume tools to reduce cycle times. But from a maintenance viewpoint, aluminum is not my friend. ALUMINUM & CONDUCTIVE ALLOYS A few years back there was a lot of talk and studies about aluminum and its positive impacts on mold-build cost and cycle times, both of whi

(1) Since most toxic monomers and oligomers. Medical plastics are strictly limited to the residual of the foregoing. (2) Plastic molding in the polymerization process inevitably comes into contact with the reactor, metal catalysts. Which often contain trace metal ions, according to the medical plastics GB. The requirement for zinc, lead, cadmium, copper, barium, tin. Other metal ions residual cases are clearly defined. (3) Requirements for medical plastics molding with high purity. Narrow molecular weight distribution. (4) Chinese plastic molding processing or modified in the process need to add various additives. Such as the amount of plasticizer in PVC medical products often as high as 30-60%. Thus required to maximize the use of toxic chemicals. To prevent long-term use or reduce the precipitation of additives to affect product performance and treatment. (5) In accordance with the requirements of medical plastic. We often need to make products with surface hydrophilicity. Anti-radiation sterilization, and other functions.
