What Is Injection Molding

An injection molding process involves the injection of molten material into a steel injection mold and then allowing the material to cool, resulting in a solid shape and then ejected by an ejection system . It is possible to manufacture a wide range of objects via injection molding, including automobile parts, toys, and medical devices.

StepDescriptionMeltingThe heated barrel and rotating screw are fed with material from the hopper. The material is melted through heat, friction, and shear force caused by the screw&#;s rotation. It is then forced through a check valve to the front.InjectionThe screw is pushed forward by a hydraulic ram, moving it from the back end to the front. This action pushes the melted material forward for injection.CoolingThe mold tool remains closed, allowing the injected plastic to cool and harden in the cavity. This stage typically takes the longest duration in the injection molding process.EjectionThe screw is moved backward to prepare for the next molding cycle. The mold tool opens, and the hardened plastic part is ejected. The tool then closes, and the injection molding process repeats from step 1.

Material, usually metal or plastic, is melted inside the barrel at the beginning of the process. A high pressure injection is then used to inject the molten material into the mold via sprue,ruuner and gate. It is opened and ejected from the mold when the matter has cooled and solidified enough. The process of injection molding can be used to produce mass quantities of objects quickly and at a reasonable cost.

An overview of injection molding history

A history of injection molding can be traced back to the s. Alexander Parkes invented a method for molding cellulose into objects in , marking the beginning of injection molding. The first plastic injection molding machine was patented by John Wesley Hyatt in .

As a result of this machine, plastic objects could be mass produced in large quantities in a short time. With the advent of mass-production of plastic products in the early s, injection molding became increasingly popular. Medical devices, automotive parts, and electronics are among the types of products injection molded today.

The Ultimate Guide to Buying The Injection Molding Machine: Everything You Need to Know

Generally speaking, customers who have been engaged in the injection molding industry for many years have the ability to judge and choose the appropriate injection molding machine for production. However, under certain circumstances, customers may need the assistance of the manufacturer to decide which injection molding machine to use, or even the customer may only have product samples or ideas, and then ask the manufacturer whether the machine can be produced, or which model is compared to be suitable for. In addition, some special products may need to be equipped with special devices such as pressure accumulators, closed circuits, injection compression, etc., in order to produce more efficiently. This shows that how to determine the appropriate injection molding machine to produce is an extremely important issue. The following information is provided for readers' reference .

How to choose injection molding machine

Whether the type and specification of the injection molding machine are correct before use will have a greater impact on the production cost, quality and production efficiency of the injection molded products.

• Model number

  Before selecting the specifications of the injection molding machine, first check the performance parameter values &#;&#;of the injection molding machine in the product manual provided by the injection molding machine manufacturer. These parameter values &#;&#;represent the main performance characteristics of the injection molding machine . According to some technical requirements of the plastic products to be produced, such as the types of raw materials for the products, the brand, the weight and the external dimensions of the products. To find the parameter values &#;&#;close to it in the manual, the injection molding machine model corresponding to these parameter values &#;&#;is the injection molding machine to be purchased.

• Specifications

  At the same time, we must also understand whether the working accuracy, speed and product accuracy level of the injection molding machine meet the molding conditions of the product.

  The key comparison data in the specifications and models include: the proportional relationship between the quality (or volume) and the external dimensions of the injection molded product and the parameter value in the equipment,

  that is, the proportional relationship between the manufactured weight and the theoretical injection volume (or volume) of the injection molding machine: product The size requirements of the length (or height) and the sum of the thickness of the forming mold (or the thickness of the mold on the moving template) and the travel distance of the moving template of the injection molding machine.

• Size

  In addition, it should also be verified that the size of the mold structure to be installed on the injection molding machine conforms to the conditions of the injection molding machine:

  1. The distance between the tie bars should be larger than the width and height of the mold to facilitate the assembly of the mold.

  2. The size of the template conforms to the size requirements when the molding die is installed and fixed.

  3. The width and height of the mold must conform to the minimum mold size recommended by the injection molding machine.
