Injection molding machine for petri dish has been widely used in various industries. But how much do you know about injection molding machine for petri dish.

Petri dish is a kind of laboratory utensils used for microorganism or cell culture. It consists of a flat disc-shaped bottom and a lid, and is generally made of glass or plastic. The materials of petri dishes are basically divided into two categories, mainly plastic and glass.

• Glass petri dishes can be used for plant materials, microbial culture, and adherent culture of animal cells.

• Plastic petri dishes may be made of polyethylene material, one-time and multiple-use ones, suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the cultivation of plant materials.

In order to make the experiment more accurate and reduce errors, most petri dishes are disposable. Our demand for petri dishes is relatively large. Therefore, an injection molding machine for petri dish is necessary.

What is the injection molding machine for petri dish used for?

Injection molding machines are the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding dies. Divided into vertical, horizontal and all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity.

The injection molding machine has the ability to mold plastic products with complex appearance, precise size, or dense texture with metal inserts at one time. It is widely used in national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture, culture, education and health, etc. With the rapid development of the plastics industry today, injection molding machines occupies an important position in terms of quantity and variety, and their total production accounts for 20%-30% of the entire plastic molding equipment, making it the fastest growing among plastic machinery at present. That’s to say, it is one of the most popular models.

As we continue to explore the unknown, our demand for laboratory consumables, such as petri dishes, is increasing. This requires factories to have injection molding machine for petri dish.

How to choose an injection molding machine for petri dish?

✅Injection volume

The injection weight is an important parameter of the injection device of the injection molding machine. The injection weight refers to the maximum expected injection weight that the injection device can reach during the maximum injection stroke of the injection screw under the condition of air injection. This parameter reflects the processing capacity of the injection molding machine to a certain extent.

✅Clamping force

Clamping force is an important parameter of injection molding machines on the market, that is, the clamping force applied to the mold by the injection molding machine. The clamping force is the same as the injection volume, which reflects the ability of the machine to process the product to a certain extent, and is used as the main parameter to indicate the size of the machine specification. When selecting the machine, try to use the value below the maximum clamping force. Sufficient clamping force is proportional to the projected area of the mold cavity, which is the projected area of the mold cavity on the separating surface of the mold.

✅Screw diameter

On a given injection device, many manufacturers offer a variety of screw diameters to choose from. The screw diameter directly affects the aspect ratio and injection capacity (and therefore also affects the injection weight).

✅Aspect ratio

The ratio of screw length to screw diameter is the ratio of screw length to diameter. If the injection molding machine has an optional screw, the screw length-to-diameter ratio is an important parameter in the selection process. The aspect ratio of 20:1 is medium quality, suitable for general injection molding. The aspect ratio of 18:1 or less is suitable for less demanding injection molding, and the larger injection weight is more important. When the screw diameter is constant, a large length-to-diameter ratio can increase the length of each section of the screw and improve the quality of plasticization. If the length-to-diameter ratio is too large, the length of the screw is longer, which increases the weight of the screw and causes the front of the screw to sag and causes the gap between the screw and the barrel is uneven, reducing its service life.
