Plastics have a very important application in the medical field. Especially in recent years, medical plastic products have been growing at a double-digit rate every year in the market. Among them, medical injection molding products have contributed the most, because injection molding products occupy medical plastic products. The most productive varieties have a share of over 70%.

The application of medical injection molding products is very extensive. According to different uses, it can be roughly divided into the following categories:Logistics, such as equipment trays, etc.; Containers, such as infusion bottles; Health care, such as fitness equipment; Organs, such as plastic joints, etc.; Surgery, such as cervical hooks; equipment, such as vaginal dilators, etc.; Classes, such as cell culture vessels, etc.; detection classes, such as insulin measuring pens, etc.; instruments, such as inhalers.

Given that some medical injection molding products have extremely stringent requirements for hygienicness and cleanliness, they must use cleanrooms when molding, and the accuracy, thinning, and high productivity requirements of medical injection molding products are all for injection molding machines, molds, and robots. The production units and their mutual matching pose challenges.

7) According to the customer's production needs, equipped with a special screw, so that customers can more convenient and effective production.

8) High standard clamping force and parallelism adjustment requirements, stable clamping state, and more stable product molding.

2. According to different needs, equipped with a special clean room to avoid product contamination.

1) On the 180T-S307M medical machine, a special sealing device is installed at the four guide rods of the movable template to prevent the guide rod lubricant from contaminating the product.

2) In the 180T-S307M medical machine, the support of the movable platen was changed to a linear guide rail to prevent the accumulation of oil stains, and sealed at the same time to prevent contact with the product.

3) In the 30T-S67 medical machine, a clean room is configured at the feeding port to prevent contamination of the product.

3. Low noise, energy saving and environmental protection.

1) Parts processing and assembling accuracy are high. The friction of the machine parts during operation is small, and the whole machine has little jitter.

2) The main power structure adopts a servo motor direct drive structure, and the power transmission process consumes less energy, making maximum use of energy.

3) All the movements are driven by the motor. During operation of the servo motor, there is little noise and no oil.

4 to adapt to the requirements of the thickness of the large cavity mold and large top output requirements

1) Increase the mold thickness by 150mm compared with the traditional model, increasing the mold selection range.

2) The use of high-torque servo motors and top-exit mechanical structures that amplify the torque to meet the demand for top-notch product output.
