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...

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...

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-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...

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...

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...

What is thin-wall injection Jul 23, 2020
Thin-wall injection molding technology is also called thin-wall plastic injection molding technology. There are three types of definitions: The ratio of flow length to thickness L/T, that is, the injection ratio of the flow length L from the melt into the mold to the farthest cavity of the cavity that the melt must be filled with the corresponding average wall thickness T is 100 or 150 is thin-wal...
