It is undeniable that injection molding machine is a great tool to produce mass products. It can make almost all things as long the material is plastic. Then about why we need to buy injection molding machine for pipette tip? There is a clear introduction in this article. Let’s get into it.

What is pipette tip?

Pipette is an indispensable experimental instrument in biological research, and its accessory suction head is also used in a large number of experiments. The suction heads on the market are basically made of polypropylene plastic (colorless transparent plastic with high chemical inertia and wide temperature range). However, the quality of polypropylene also varies greatly: high quality suction heads are generally made of natural polypropylene, while low-cost suction heads are likely to use recycled polypropylene plastic (in this case, we can say that the main component is polypropylene). In addition, most suction heads also add a small amount of additives in the manufacturing process.

It is hard to believe that a simple plastic molded disposable suction head is the foundation of the world of molecular biology, chemistry and medicine. Yes, we're talking about pipette suction. These suction heads create a reliable and accurate pipetting system. Pipette suction heads are divided into three different types, including non sterile suction head, pre disinfection suction head and filter suction head.

Working principle of injection molding machine

During the operation of the injection molding machine, when the screw rotates, the plastic will produce friction and mutual movement on the inner wall of the barrel, the bottom surface of the screw groove, the screw edge propulsion surface and between the plastic and the plastic. The forward movement of plastic is the result of this combination of motion, and the heat generated by friction is also absorbed to raise the temperature of plastic and melt plastic.

The design structure of the screw will directly affect the degree of these effects. At the same time, the rotation of the screw will shear the molten film between the solid bed and the inner wall of the barrel, so as to melt the solid between the molten film and the interface of the solid bed. As the spiral shape of the solid bed moves forward, the volume of the solid bed gradually decreases and the volume of the molten pool gradually increases.

Words at the end

Pipette tip is a product needed in large quantities, only the injection molding machine can achieve mass production of it. If you have any needs of mass production, welcome to contact NINGBO LISONG INJECTION MOLDING TECHNOLOGY CO., LTD. It has types for different products like disposable forks.
