​ When the mold temperature is not high, resins whose material fluidity deteriorates significantly, such as polycarbonate PC, polyphenylene ether PPO, polyethylene terephthalate, commonly known as polyester resin PETP, etc., require the mold temperature to be heated to 80 degree or above (use a mold temperature regulator). ​​

Plastic gear parts injection molding process and material analysis. Plastic gears are developing toward larger sizes, more complex geometries, and higher strength, with high-performance resins and long-glass fiber-filled composites playing an important role. Plastic gears have experienced a change from new materials to important industrial materials in the past 50 years. Today they have penetrated

Not enough (lack of glue) Process problems: plasticizing temperature is too low, nozzle temperature is too low, injection time is too short, injection speed is too slow, mold temperature is too low. Mold problems: the runner is too small, the gate is too small, the gate position is unreasonable, the exhaust is poor, and there

Solutions to bubbles appearing during injection molding Causes and solutions of bubbles When the wall thickness of the product is large, the outer surface cools faster than the central part. Therefore, as the cooling proceeds, the plastic resin in the central part shrinks and expands toward the surface, causing insufficient filling of the central part.

Two color mold design and injection should pay attention to matters include:

Plastic product structure design Key points of plastic product structure design Holes that are parallel to the opening direction of the mold are usually formed with a core (can be inlaid or extended) or by punching or inserting. Holes that are not parallel to the opening direction of the mold are usually made with rows

What issues need to be paid attention to when producing PC polycarbonate products? PC has excellent performance, high transparency, good impact toughness, creep resistance, and wide operating temperature range. Process characteristics of PC: The melt viscosity is less sensitive to shear rate, but more sensitive to temperature, has no obvious melting point, the melt viscosity

The proportion of plastic materials in our daily life is getting higher and higher, and the requirements for their quality are also getting higher and higher. As an important production method, injection molding is becoming more and more urgent to improve technology, and the influencing factors of injection molding products. There are many, and the

The most complete plastic mold design process in history The task statement for molded plastic parts is usually proposed by the part designer, and its content is as follows: Usually, the mold design task sheet is proposed by the plastic parts craftsman based on the task letter for molding plastic parts. The mold designer designs

I believe who use SOLIDWORKS know that our hard work is all so that the final parts can flow smoothly in the application scenario and be completed in one go. At the software level, we continue to optimize functionality and ease of use to reduce the workload of engineers. But from design to reality, you
