🔥 🔥 Gate location and size 🔥 🔥 ✅ 1) Place the gate at the thickest part of the product. Pouring from the thickest part can provide better filling and holding pressure effects. If the holding pressure is insufficient, the thinner area will solidify faster than the thicker area. Avoid placing the gate at the place where the thickness changes suddenly to avoid hysteresis or short shots. ✅ 2) If possible, pour from the center of the product. Placing the gate in the center of the product can provide equal flow length. The size of the flow length will affect the required injection pressure. Central pouring makes the holding pressure uniform in all directions, which can avoid uneven volume shrinkage. ✅ 3) When the plastic flows into the runner, the plastic first cools down (cools) and solidifies when it approaches the mold surface. When the plastic flows forward, it only flows through the solidified plastic layer. Because plastic is a low heat transfer material, solid plastic can still flow after forming an insulating layer and a retaining layer. 🔶 🔶 The size of the gate can be determined by the cross-sectional area and the gate length. The following factors can determine the optimal gate size: 1️⃣ Rubber flow characteristics 2️⃣ Mold thickness 3️⃣ Amount of rubber injected into the mold cavity 4️⃣ Melting temperature 5️⃣ Mold temperature #plastic #plastic #plastic #mold #cavity #mould #tooling #tool #gate #gate #flow #flow #temperature #injection #molding #Injectionmolding

Twin sheet thermoforming can produce durable, lightweight plastic parts that are hollow inside for insulation, airflow, or structural rigidity. The tooling costs are lower than blow molding, and the turnaround times are faster than rotational molding. https://bit.ly/3TTnuZP #thermoforming #thermoformer #plastics #partdesign #molding

The mold is a hollow metal block into which the molten plastic is injected from a fixed shape. Although they are not illustrated in the figure below, there are actually many holes drilled in the block for controlling the temperature through hot water, oil or heaters. The molten plastic flows into the mold through the gate and fills the cavity through the runner and gate. Then, after the cooling process, the mold is opened and the ejector pin of the injection molding machine pushes the ejector plate of the mold to further eject the molded product. #kayoumould #plasticmold #automotive #tooling #injectiontooling #injectionmold #precisionmold #highquality #competitiveprice #Tooling factory #professional cleaingRobot #handholdScaner #outdoorbattery# bella@kayoumold.com www.kayouplasticmould.com

Did You Know? Compression molding is a key process used to shape thermoset plastics, and it’s responsible for creating some of the most durable and heat-resistant products around. Here’s how it works: Preform Stage: A measured amount of thermoset plastic (often in the form of a preform or powder) is placed into a heated mold.  Compression: The mold is closed, and pressure and heat are applied. The plastic softens, flows, and fills the mold, taking the shape of the cavity.  Curing: The plastic undergoes a chemical change (curing), hardening it into a tough, rigid material.  Ejection: After cooling, the mold opens, and the final product is ejected. What’s it used for? Compression molding is perfect for creating large, strong parts like:  - Automotive components   - Electrical insulation   - Industrial parts  Want to learn more about plastic manufacturing?

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

Mold making in progress. Pleasure to the eyes. Alright, if you are not a technical weirdo like me, this video will not bring any added value. But it is what it is. I can watch metal transformation all day long. And what is even better, after the metal transformation we will use these parts to produce plastic components 🤯😏 Hit me up with your new idea for plastic and/or metal parts. Together we will make the drawings alive. #plastics #injectionmolding #manufacturing #injectionmoulding

#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.

💡 #KnowTipsWednesday: The injection molding gate is a small, critical opening that directs molten plastic into the mold cavity. But did you know? Improper gate placement can lead to uneven plastic flow, which affects the quality of your final product. ✅ Pro Tip: Always place the gate in the thickest section of the part to ensure even filling and minimize defects.

🎯 3️⃣ kinds of gating system for plastic injection mold 👇 👇 👇 ✅Edge gate mold: runner and gate are on the parting line , will demould together with part when mold is opened , the design is the simplest and easy to process, also the cost is low; ✅Pin-point gate mold:runner and gate are not on the parting line , generally they are on part directly,so need to design one more group gate parting line,the design is kind of complex and hard to machine; ✅Hot runner mold :Both hot runner mold and pin-point gate mold have approximately the same structure,the biggest difference is that the runner is on the single thermostatic hot runner plate or multi- thermostatic hot runner plate, and demould without cold slag,runner and gate are on the part directly, so no need to demould for runner, this system is also called "no gating system". ☺️ #InjectionMolds #Manufacturing #Precision mold #Engineering #Mold Design #Tool  #Plastic part #Plastic mold  #Automotive parts mould, #household appliance mould,  #medical mould, #Electronics mould #Mold maker
