What are the differences between plastic mold and injection mold?
When a product is born, mold opening is essential. When we need to find a mold opening factory, we often think that injection mold and plastic mold are the same. To understand the difference between plastic mold and injection mold, please read this article,

Plastic mold, a combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming molding, mainly includes a female mold with a variable cavity composed of a female mold combination substrate, a female mold component and a female mold combination card board, and a male mold with a variable core composed of a male mold combination substrate, a male mold component, a male mold combination card board, a cavity cutting component and a side section combination board. Coordinated changes of the punch, die and auxiliary molding system. It can process series plastic parts of different shapes and sizes.

Injection mold is a tool for producing plastic products; It is also a tool to endow plastic products with complete structure and precise size. Injection molding is a processing method used in the mass production of some complex shaped parts. Specifically, the heated melted plastic is injected into the mold cavity by the injection molding machine under high pressure, and the molded products are obtained after cooling and curing. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a gating system and a mold cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic products. In order to reduce the heavy workload of mold design and manufacturing, most injection molds use standard mold bases.

It can be seen from the above that there are still some differences between plastic mold and injection mold, which is also convenient for us to communicate with plastic mold manufacturers and avoid mistakes.

Plastic molding and injection molding are two widely used manufacturing processes in the plastic industry. Although the terms are sometimes used interchangeably, they are different in terms of their processes and applications. Here are some of the key differences between plastic mold and injection mold.

  1. Process: Plastic molding is a process in which plastic is heated and shaped using pressure, while injection molding is a specific type of plastic molding that involves injecting molten plastic into a mold cavity under high pressure.
  2. Application: Plastic molding is used for a variety of applications, including producing large objects like car bumpers, while injection molding is used for producing small, intricate parts such as gears, caps, and medical devices.
  3. Cost: Injection molding is typically more expensive than plastic molding, but it offers a higher level of precision and produces parts with a more consistent quality.
  4. Tooling: The tooling for plastic molding is usually less complex than that of injection molding, which requires precision molds that can withstand high pressure and temperature.
  5. Cycle Time: Injection molding generally has a shorter cycle time than plastic molding due to the use of high pressure and quick cooling.
  6. Material Selection: Injection molding can use a wider range of materials, including engineering-grade thermoplastics, while plastic molding is limited to a few materials.

In summary, both plastic molding and injection molding have their advantages and disadvantages, and the choice between the two depends on the specific needs of the product being produced. While plastic molding is suitable for larger, simpler products, injection molding is better suited for smaller, more complex parts that require a high level of precision and consistency.
