🔥🔥High gloss seamless injection mold and molding technology 🔥🔥 🔉🔉We compare the traditional injection molding process to illustrate the characteristics of the high-gloss seamless injection molding process. In the traditional ordinary injection molding process, when the mold temperature is set low, although warping and shrinkage marks can be reduced and the molding cycle can be shortened, it is easy to produce weld marks and material lines, dark gloss, rough surface and other poor appearance quality. 💚💚On the contrary, when the mold temperature is set high, the appearance quality of the product surface can be improved, but it is easy to produce warping, shrinkage marks, poor dimensions, etc., while extending the molding cycle and increasing costs. 💛💛 🔉🔉First, high-temperature water or steam (such as 150°C) is introduced into the mold before injection to make the mold temperature reach a viscosity flow temperature that exceeds the resin thermal deformation, and then the molten resin is injected, so that the material temperature at the front end of the confluence can be maintained in a viscosity flow state, and a molded product with no confluence line (weld line) and good surface quality will be formed. After the molten resin is injected, the cooling process begins. 🧡🧡Use cooling water to quickly drop the mold temperature to below the resin thermal deformation temperature (such as 40°C). In this way, the molding cycle can be shortened by accelerating the curing speed of the resin, and problems such as warping and sinking can be solved. 🔉🔉High-gloss seamless injection molding can eliminate weld lines, weld marks, ripples and silver lines on the product surface, completely solve the surface shrinkage phenomenon of plastic products, and make the surface finish of the product reach the mirror level, which can almost completely reproduce the surface state of the mold and achieve a seamless effect. 🔔🔔 #molding #molding #molding #mold #injection #injection #injectionmolding #mold #mould #tooling #highgloss #highgloss #temperature #technology #process #process #cooling #shrinkage #shrinkage

💥Causes and solutions for bubbles in injection molded parts 💥 🥀1. What are bubbles (appearance) 🥀 Bubbles refer to a phenomenon in which the surface of a molded product bulges or gas is trapped inside. As shown below: 🥀2. Causes of bubble generation 🥀 ❌ (1) Air entrainment 1.1. Air entrainment in the barrel: * Screw speed is too fast * Back pressure is too low * Resucking volume is too large 1.2. Air entrainment in the barrel: * Screw speed is too fast * Back pressure is too low * Resucking volume is too large ❌(2) Resin degradation 2.1. Barrel temperature is too high 2.2. Barrel residence time is too long 2.3. Screw diameter is too large 2.4. Other easily degradable materials are mixed ❌(3) Material is not dried ❤️💚3. Countermeasures for bubbles💚 ❤️ ✅ (1) Reduce air entrainment 1.1. Reduce air entrainment in the barrel: Reduce screw speed, increase back pressure, and do not set the resucking volume too high. 1.2. Reduce air entrainment in the mold cavity during filling: Reduce injection speed, adjust gate position, size and shape, and adjust the main channel demolding slope. The key is to grasp the flow pattern through filling tests, and then establish corresponding countermeasures based on this. ✅(2) Inhibit material degradation 2.1. Reduce the barrel temperature (within the recommended operating temperature range. Do not reduce it too much). 2.2. Select a reasonable screw diameter 2.3. Thoroughly clean the barrel and various auxiliary machines to prevent mixing. ✅(3) Improve exhaust conditions ✅(4) Use high-viscosity materials or add additives High-viscosity materials are generally not prone to voids, so trying to use this material is also a method, and additives such as glass beads can also be added. #injection #mold #injectionmolding #material #mould #tooling #bubble #generation #solutions #cavity #bubble #generation

Silicone mold making process 🚀🚀 Silicone mold making materials include: ABS, PC, PP, PMMA, PVC, rubber, high temperature resistant materials, etc. 🌈💡 🔷➡ 1. Prototype manufacturing: According to the 3D drawings provided by the customer, the prototype is manufactured through CNC processing, SLA laser rapid prototyping or 3D printing. 🔷➡ 2. Casting silicone mold: After the prototype is manufactured, the mold frame is manufactured, the prototype is fixed, and silicone is poured. After drying for 8 hours, the mold is opened to take out the prototype, and the silicone mold manufacturing is completed. 🔷➡ 3. Injection molding: Inject liquid plastic material into the silicone mold, and after curing in a constant temperature box at 60°-70° for 30-60 minutes, it can be demolded. If necessary, it can be secondary cured in a constant temperature box at 70°-80° for 2-3 hours. Under normal circumstances, the service life of silicone molds is 15-20 times. #process #process #mold #mould #tool #tooling #prototype #prototyping #manufacturing #silicone #casting #injection #molding #siliconemold #plastic #3Dprinting #CNC

⚒ Sheet metal forming process refers to the process of deforming metal sheets into specific shapes and sizes by processing them. Commonly used sheet metal forming processes include shearing, punching, bending, stretching, compression, etc. 🤛 1. Shearing: Cut the metal sheet into the required size or shape through a shearing machine with a correspondingly shaped tool. ✂ 2. Punch: Use a punching machine to punch holes of various shapes or other concave and convex shapes into the metal sheet to meet production needs. 🗝 3. Bending: Use a bending machine or manual operation to bend the metal sheet according to the required angle or arc. 🔨 4. Stretching: Use a stretching machine to stretch and deform the metal sheet within a certain range to achieve the forming process of the sheet. 🚀 5. Compression: Roll or shape the plate through a blank compressor, and process the flat plate into a curved or tubular component. 🌠 #Cut #Cut #Sheet #metal #forming #Sheetmetal #process #Shearing #Punch #Bending #Stretching #Compression #machine #tool #mold #die #engineering #engineering

💥 Working principle of stamping die 💥 The working principle of the stamping die is mainly to apply pressure to the material through a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts. 🚀 🛰 The specific process is as follows: 💚 💛 1. Pressing and feeding. Material is fed into the mold, usually through action between an upper and lower mold. 💚 💛2. Positioning. The material is precisely positioned in the mold to ensure stamping accuracy. 💚 💛3. Suppression. A male mold is used to apply pressure to the material, causing it to enter the female mold cavity and produce the desired shape or size change. 💚 💛4. Discharge materials. After stamping is completed, the material is removed from the mold. #stamping #die #Pressing #feeding #mold #material #Positioning #produce #sheet #metal #sheetmetal #mould #tooling
