The second shot's process variables include the second material's melt temperature, injection pressure, and speed. These factors may affect the part's overall quality and the adherence of the two materials. Increased injection speed and pressure can strengthen the bond between the two materials but also raise the possibility of cavities or delamination. To achieve adequate flow and adhesion to the first material, the melt temperature of the second material needs to be carefully managed.

The width and height of the mold must conform to the minimum mold size recommended by the injection molding machine. Too small is not acceptable.

Some engineering plastics require higher injection pressure and suitable screw compression ratio design to have better molding effect, so in order to make the finished product injection better, the selection of the screw also needs to consider the required ratio of injection pressure and compression ratio. .

Last but not least, this injection moulding can assist companies in saving money in several ways. We can reduce labour costs, material prices, and energy costs by shortening the production process, increasing manufacturing efficiency, and minimizing material waste. Businesses can also distinguish themselves in the market and charge more for our goods by making higher-quality parts with more complicated geometries and various material qualities.

In this case, it may be necessary to check whether the injection volume and injection speed of the machine are sufficient, whether it needs to be equipped with an accumulator, closed-loop control, etc. Screws that can provide higher injection pressures generally have lower injection speeds, and conversely, screws that can provide lower injection pressures generally have higher injection speeds. Therefore, when selecting the screw diameter, the injection volume, injection pressure and injection speed (injection speed) should be comprehensively considered and weighed.

Since there are many types of injection molding machines, it is necessary to correctly judge which type of injection molding machine or series should be used to produce the product, such as general thermoplastic or bakelite or PET material, single color, double color, multi-color-color, sandwich or mixed color . In addition, some products require conditions such as high stability (closed circuit), high precision, ultra-high injection speed, high injection pressure or rapid production (multi-circuit), and the appropriate series must also be selected for production.

The electric press, also known as Electric Machine Technology (EMT), reduces operation costs by cutting energy consumption and also addresses some of the environmental concerns surrounding the hydraulic press. Electric presses have been shown to be quieter, faster, and have a higher accuracy, however the machines are more expensive.

The injection pressure, speed, and melt temperature are important process variables impacting the first shot. These variables affect how the first material flows and is packed, which might impact the consistency and quality of the parts. Higher injection pressure and speed can enhance the first material's packing and raise the possibility of flash or sink markings. To ensure that the first material flows properly and completely fills the mould cavity, the melt temperature must be carefully regulated.

The company's main business verticals are automotive, packaging, medical, electrical, sports and leisure, toys, construction, etc.

The opening and closing stroke should be at least twice the height of the finished product in the opening and closing direction, and should include the length of the vertical runner; the holding stroke should be sufficient to eject the finished product.

Servo injection molding machines claim to take advantage of the best features of both hydraulic and electric systems, but in actuality use almost the same amount of electricity to operate as an electric injection molding machine depending on the manufacturer.

The mold and finished product should determine whether the "opening stroke" and "clamping stroke" are sufficient to remove the finished product.

So far, the specifications of the clamping unit have been preliminarily determined, and the tonnage of the machine has been roughly determined. Next, the following steps must be performed again to confirm which injection unit has a better screw diameter.

Today, I would like to introduce you to the world's top 10 Plastic injection molding machine manufacturers, hoping to help you.

The mould temperature, cooling time, and ejection time are additional process variables that may impact the general quality of these injection moulded parts. The mould temperature needs to be carefully managed to ensure that the materials are filled and packed properly. The cooling period should be carefully calculated to reduce warpage and increase cycle duration. The ejection time needs to be precisely set to prevent causing damage to the pieces when taking them out of the mould. Two types of 2k injection molding process parameters may be made: those that influence the first shot and those that influence the second shot. The first injection of the first substance is referred to as the "first shot," and the subsequent injection of the second material is called the "second shot."

The clamping force of the machine should be greater than the clamping force. For the sake of safety, the clamping force of the machine usually needs to be greater than 1.17 times of the clamping force.

Finished weight and number of cavities are used to determine the required "shot volume" and to select the appropriate "screw diameter".
