What Problems Will Occur in Processing of Cold #Extrusion #Press https://lnkd.in/gSjebbJ7 #coldextrusionpress #coldforgingpress #hydraulicpress During the processing of cold extrusion press, the following problems may occur: 1. the mold problem Mold wear: Due to the large friction between the metal blank and the die during cold extrusion, it is easy to cause die wear. Mold wear will affect the dimensional accuracy and surface quality of parts, reducing the service life of the mold. Mold rupture: During the cold extrusion process, the mold is subjected to tremendous pressure, and if the mold is not strong enough or the design is not reasonable, it is easy to rupture. A cracked mold will not only damage the equipment, but also affect the production schedule. Elastic deformation of the mold: When the mold is subjected to greater pressure, elastic deformation may occur. The elastic deformation of the mold will lead to a decrease in the dimensional accuracy of the part, which will affect the product quality. ......... In order to avoid these problems, in the processing of cold extrusion press, it is necessary to select the appropriate die material and structure, optimize the extrusion process parameters, ensure the normal operation of the equipment, and strengthen the quality control of the production process.

Not all plastics are molded equal. When choosing between structural foam molding and high-pressure injection molding, it’s all about your product’s needs. Structural Foam Molding is ideal for larger parts and uses lower pressure, meaning less stress on the molds. Need big, strong parts without the high tooling costs? This is your process. On the flip side, High-Pressure Injection Molding is all about speed and detail. If you’re cranking out small, intricate parts, it’s the way to go. 🔧 Choosing between the two? Think about volume, size, and complexity. Every product has its perfect match!

#snsinstitutions #snsdesignthinkers #designthinking ARTICLE ABOUT VERTICAL PLASTIC INJECTION MOULDING MACHINE A vertical plastic injection molding machine works by injecting molten plastic into a mold in a vertical direction, then cooling and solidifying the plastic to create the final product. The process involves several steps, including: Die installation: The die is installed in the center between the upper and lower die. Mold closing: The upper form closes the mold at a low pressure and slow speed. Injection: The injection pressure, time, and position are adjusted based on the product's material, shape, and size. The injection button is then pressed to complete the injection. Solidification: The plastic cools and solidifies to take the shape of the mold cavity. Mold opening: The two halves of the mold are opened to release the solidified plastic.

𝐑𝐮𝐛𝐛𝐞𝐫 𝐄𝐱𝐭𝐫𝐮𝐬𝐢𝐨𝐧 Let's take a closer look at a fundamental Production process in our Compression molding: Extrusion. What it is? It is a process that allows rubber materials to be transformed into a smaller product with a specific shape. How does it work? It involves using an extrusion machine to force raw compounded material through a shaped die using heat and a high level of pressure. In this way it is possible for us to obtain a very easily malleable rubber part which is then put in another mold and vulcanized in Compression machines to fix all the mechanical properties and harden it into the desired product. What are the benefits of extruding? 1. The finished parts are highly resistant to chemicals, heat, cold, aging, fatigue, friction, abrasion wear and tear and therefore ideal for use in a myriad of harsh or extreme conditions. Moreover, extruded rubber products are flexible, extremely durable and long-lasting. 2. The process is more efficient in terms of reduced waste volumes hence more economical.

THERMOFORMING Thermoforming refers to a fabrication process which essentially involves the following three steps: 1.Heating of a plastic sheet to its softening temperature; 2.Forcing the hot, flexible material against the contours of a mold; 3.Cooling the sheet to reatin the mold’s shape and detail. The types of thermoforming processes are vacuum forming, pressure forming, melt phase thermoforming, and matched mold forming. Examples of applications of thermoformed parts are: #thermoforming #plasticpackage #knowhow #applications

Final Steps: From Curing to Shipping 📦✈ Here’s how we complete the process: 8. Demolding & Curing Once the polyurethane has solidified and reached a minimum strength, the mold is removed. The material, now solid, undergoes curing and/or post-curing to achieve its final properties. This involves conditioning at specific temperatures and times based on the PU type. 9. Finishing The product is perfected in the machining department. Rolls can be finished with cylindrical or crowned surfaces, various groove patterns, and specific surface roughness levels. 10. Packing & Control We conduct a final quality control and package the products appropriately. 11. Shipping The finished products are then shipped to our valued customers.

Important properties for injection molding materials Choosing an injection molding material requires one to think about the purpose of the part. Does it require strength, toughness or elasticity? Should it exhibit high or low friction? Does it need to be chemically resistant or heat resistant? An injection molding material should be chosen only when the desired material properties have been identified. Material properties to consider may include:
