When it comes to molding materials, everyone can immediately guess that stainless steel. However, it takes work in the molding industry to know that there are many different types of steel (steel marks). And of course, each type of mold uses different steel marks. Even each mold assembly detail can be used different types of steel.
The purpose is nothing more than to ensure the quality of molds, product quality output. The right type of steel also determines the durability of the mold and the cost that your company has to spend to make the mold.
The steel used in mold making shared by VCC, will help you gain more knowledge about the types of steel as molds.
Basic parts of the mold
The pattern is pieced together by many different details. This includes the following basic parts:
- Mold shell
- Mold Core
- Molding Components
The mold shell is the part of the largest size, which determines the size of the entire mold set. Steel as a mold shell is an important factor affecting the quality and cost of the whole mold set.
The core of the mold is in direct contact with the product, deciding the quality of the product created. Often use high quality steel to ensure product quality.
The components assembled in the mold are very diverse, so the mold manufacturer will choose the type that is suitable for each location.
Usually steel as molds people use S55C steel label to make mold shells. S55C has strong antioxidant, high intensity, is a common steel for mold shells. Because the shell is already thick, there is no high requirement for hardness. The core and the interior parts use higher hard steel such as SKD11, NAK80, ELMAX,…
Selection of steel as a mold for the purpose of use
Types of steel making plastic molds
Plastic molds are molds used to produce plastic products. Operate by attaching the mold to the corresponding plastic press. The combination of plastic presses and molds will serve the process of mass production or continuous production.
Some common plastic mold steels: 1.2083, SUS420J2, P20, 1.2311, NAK55, NAK80,…

Types of steel for cold stamping mold
Cold stamping molds, also known as stamping molds,are used to produce products of sheet metal or thin alloy plates. Details of the VCC Molds stamping mold were shared in the previous article. If you would like to request a stamping molding service as required,contact us.
The stamping mold consists of 2 parts: pestle and mortar. The pestle will act the force on the metal plate placed above the mortar, forming a model product shape in the mortar section.
Common steel labels for cold stamping molds are SKD11, 1.2379, Cr12MoV, D2, SK3, SKS3, SKS93, DC53, SLD,…
Types of steel for hot stamping mold
Hearing the name of the mold, you must also guess the type of steel that makes the hot stamping mold need to withstand heat. Hot stamping molds make the product by acting on the metal block in a hot state.
The material workpiece is heated to the right temperature, then put into the mold. The mold will stamp out the product shape until the workpiece cools. The product is formed with the same shape and size as the sample design.
Common steels for hot stamping molds: SKD61, H13, 1.2344, 4Cr5MoSiV, SKT4, DH2F,…
Selection of steel as mold by quality
There’s a good kind of thing about everything. Depending on the customer’s requirements, the mold manufacturer advises on which type of steel to use. At VCC Molds,we put quality first, so the mold will be used the most suitable quality steel.
Steel as a common mold
Conventional molding steel remains a less corrosive type of steel, easily machining, polishing and cooling. Don’t be in a hurry to think: isn’t this steel so good? Its downsides are just below.
The hardness of the steel also affects the durability of the mold. This type of conventional steel has low hardness, gloss is not high.
This type of steel has a relatively low price, so many manufacturers, despite the quality, choose these steel marks to reduce the price of the mold.
Customers need to carefully consider when choosing a reputable mold manufacturing company.
Common steel labels: S45C, SCM440, S50C,…
High quality molding steel
High requirements for molds should choose high-quality steel marks.
+ Higher steel hardness
Create the perfect glossy surface
+ Good mechanical properties such as high abrasion resistance, impact resistance, high temperature resistance
+ Create a persistent pattern.
+ Can be carried out methods such as nitrogen permeability to increase hardness, chromium plating, nickel plating to protect the mold….
The downside is the high price. But for a manufacturing company, product time and quality are two advantages that win customers’ hearts, increasing the competitiveness of the business. Businesses should not be cheap but forget about quality.
High quality molding steel labels: SKD11, SKD61, SKD62, 2316, 2083, NAK80,…
