Main points related to the design of gear mold Jul 23, 2020
1. Gate: generally, 3-point or 6-point is used for balance. For micro gears, usually single point is used. 2. Mold cavity: usually for 1~4 cavities. Small gear can reach 6 or 8 cavities; Different shapes of gears could be 3 cavities. The most representative is 4 cavities. 3. Ejection: normally use center ejector sleeve and ejector pin. For the helical gear, a bearing must be added to assist the ej...

How many under-cut structure you have seen? Jul 23, 2020
In plastic product, there are some under-cut structure. How many under-cut structure you have seen? Some product only have one under-cut, some product has more than one under cut surface, some product whole four surroundings has under-cuts, some product has under-cut in the under-cut. What's the meaning of under-cut? Under-cut means when you see from the top view, the highest point is the referenc...

Advantages of using small gate for injection molding-2 Jul 23, 2020
③Because the small gate has a small volume and fast freezing, when producing certain products, it is not necessary to wait for the entire solidification of the product after the small gate is frozen. As long as the external cured layer has sufficient strength and rigidity, the product can be demolded, thereby Shorten the molding cycle and improve production efficiency. ④In the multi-cavity unbalan...

Cautions for PEEK material injection molding Jul 23, 2020
PEEK polyetheretherketone resin was first used in the aerospace field, replacing aluminum and other metal materials to manufacture various "aircraft parts." In the automotive industry, PEEK resin has good friction resistance and mechanical properties. The raw materials, the bearings, gaskets, seals, clutch gears and other components manufactured by it are widely used in automobile transmission, br...

Advantages of using small gate for injection molding-1 Jul 23, 2020
The gate is a very important material flow channel in the pouring system. Except for the main channel gate, most gates are the smallest cross-sectional area in the pouring system, and the value is generally only 3%-9% of the cross-sectional area of the runner . For plastic melts that obey Newtonian flow laws, since the viscosity is independent of the shear rate, a large gate cross-sectional area c...

Solutions and precautions for common problems of hot runner molds (2) Jun 12, 2020
Today we are go on with discussion to solutions and precautions for common problems of hot runner molds 5. Silver streak around the gate (area within 50mm from the center of the gate) Reason: The plastic at the front of the needle core was punched into the mold cavity; the injection was started before the valve needle was fully opened (the injection speed is too fast). Solution: Reducing the nozzl...

Why the plastic parts have mixed color? Jul 23, 2020
Sometimes when we make injection parts, we can find some parts have mixed color, why this happens? The reason may be as below: 1. plastic material is mixed with master color or toner. 2. plastic material was decomposed and carbonized. 3. it was polluted when adding material or changing material 4. the material itself is not pure, has mixed material other material Green Vitality has rich experience...
Working principle of injection molding machine May 30, 2020
The basic working principle of the injection machine can be understood as that after the plastic raw materials are uniformly plasticized in the barrel, they are injected, molded by flow, filled with pressure, and cooled to form injection products. Under the action of the screw, the granular plastic stored in the hopper continuously moves along the screw groove. Due to the comb...
