For Injection mold, the main metal used in steel.
There many different steels are used, for example, P20, 1.2311,718H,1.2738, H13, 1.2344, 2316,S136, etc..
Usually for mould based, the steel will be SC45#,P20 or 1.2311.
For daily household product, the stell will be 718H,1.2738
For PVC material ,steel will be 1.2316 or S136,
For food product mould, for example preform mould or food contaier mould, the steel will be S136. this is stainless mould steel.

Plastic injection molding is a process for producing parts by injecting materials like metals, glasses and thermoplastic, into mold cavity. Injection molds are used to make things like bottle caps, mechanical parts, automobile dashboards and packaging.
One can use a shot utensil for injection molding. Many carpenters and renovators use a mold injection to closely mold two things together. Glue may also be used as well for a better grip.
An injection mold is a closed mold where the material to be molded into that specific design is fed through a fill hole in the mold. This is a common process for plastic goods but is also used for cars' body panels.
Such as P20,718,NAK80, 2344,8407,S136...
Injection mold
The amount of pressure used in injection molding is a critical factor in the success of the molding process. Too little pressure can result in poor-quality parts with defects, such as incomplete filling of the mold cavities or inadequate bonding between the plastic and the mold. Too much nozzle pressure can cause damage to the mold and the injection molding machine, as well as excessive wear and tear on the equipment. The amount of pressure used in injection molding is determined by several factors, including: a. The type and viscosity of the plastic material. b. The size and shape of the part being molded. c. The design and construction of the mold. d. The injection molding machine. e. The complexity of the part being molded. In general, the pressure used in injection molding should be sufficient to fill the mold cavities and create a strong bond between the plastic and the mold.
The three different types of metal molds are injection molds, blow molds, and compression molds. Injection molds are used for creating complex shapes by injecting molten metal into a mold cavity. Blow molds are mainly used for hollow objects, where air is blown into a heated plastic to expand it into the mold. Compression molds involve placing a material in a heated mold cavity, where it is then compressed to form a specific shape, commonly used for thermosetting plastics.
Injection molding plastic is a tool used to mold hard material through thermal heat, for example steel or aluminum are not metals that could be heated using the tool which makes the material easier to manipulate or mold into varies of shapes. The tool is often seen used by engineer.
How many products an injection mold can make is mainly determined by the following factors: a. The material of the plastic product. b. The structure of the plastic product. c. The material of the injection mold. d. The structure of the injection mold. e. The number of holes in the injection mold. f. The type of flow channel of the injection mold. How does the material of a plastic product affect mold life? The material of a plastic product can have a significant effect on the life of the injection mold used to produce the product. a. The additives of some products are corrosive, which will cause a certain degree of corrosion to the mold during the mass production manufacturing process. Which can also lead to decreased mold life. b. Harder materials, such as some products have higher requirements on strength and need glass fiber-filled materials. Such as (PA+GF, PBT+GF, etc.). , can wear down the mold more quickly than softer materials, which may cause the mold to need to be replaced sooner. c. Additionally, some materials may be more prone to sticking to the mold, which can also lead to decreased mold life. The material fluidity of some products is not good, and the injection pressure needs to be increased during production. If the production is continued under high injection pressure, it will also affect the number of injection molded parts. d. Some products are made of high-temperature materials, such as PPS, PPSU, PPO, etc. Which requires a high temperature during production, and the injection mold also needs to maintain a stable high temperature, which will also reduce the number of products made by the injection mold. In general, it is important to carefully consider the material being used for a plastic product and its potential impact on mold life when designing and manufacturing the product.
It is an appliance used in the plastic injection mold industry. It is used in the coolng process for the manufacture or plastic items.
A plastic injection mold is an engineered piece of custom equipment used in manufacturing. It is a series of steel or aluminum plates with a cavity in the center of them machined into the shape of the part being produced. Molten plastic is injected under high pressure filling the cavity, after which the plastic cools and re-solidifies. The mold then opens and ejects the part out with the help of an injection molding machine.
The type of injection mold runner can affect mold life in several ways. A cold runner mold uses a separate, unheated channel to deliver plastic to the mold cavity.Which can reduce the risk of warping or other damage to the mold caused by exposure to high temperatures. This can help extend the mold’s lifespan. On the other hand, a hot runner mold uses heated channels to deliver molten plastic to the mold cavity.Which can increase the risk of heat-related damage to the mold. This can decrease the mold’s lifespan. Additionally, the design and construction of the runner itself can impact its durability and lifespan. Overall, the type of runner used in an injection mold can have a significant effect on its life.
