What material to use to make the mold 10, what material to use to make the mold

Steel is definitely not a good idea!! To 60HRC, it is brittle and can not be used, and it is recommended to use CR12MOV for toughness and hardness, and if you consider the cost, you can use CH-1 air-cooled steel.

7Crsimnmov (code CH-1) steel is an air-quenched micro-deformation low-alloy steel and flame-quenched steel, which can be locally quenched by flame to harden the cutting edge part of the die. The quenching temperature (800 1000 has good hardenability and hardenability (up to 60 HRC), high strength and toughness, and can be repaired after chipping. It can replace CRWMN and CR12MOV steel to make punching dies with complex shapes.

Recommended heat treatment process for CH-1 steel: quenching temperature 900 920, oil cooling, 190 200 tempering 1 3 hours, hardness 58 62 HRC. Some of our large-scale automotive panel molds here use this steel, whether it is used or repaired, the feeling is okay, of course, it is not comparable with CR12MOV.

The hardness after the general quenching and tempering treatment (quenching + high temperature tempering) is about 38-42hrc, if you overheat to 60hrc, it is basically useless, crispy as a small crisp, haha.

In addition to high-quality alloy steel (gear material) and hot work die steel (die-casting mold) commonly used die steel, there are only a few kinds of mold steel: CR12, 40CR, 45, and there are only a few heat treatment methods, normalizing, quenching and tempering, carburizing, but 45 is difficult to 60, and high-quality alloy steel can reach 56-58.

Cr12MOV is recommended, the quenching hardness can reach HRB58 or above, and the toughness is better than CR12.

40cr and steel 45 can't reach such a high hardness.

The guy upstairs was right when he said that 45 is the so-called 60 degrees.

When it reaches 60 degrees, it cracks.

After the processing of No. 45 steel, it is heat treated.

What materials to take to be able to make a model by hand, and the expert will give you a thank you in advance.

To make an airplane (fixed-wing), materials: KT board or EPP foam, carbon fiber tube, Kevlar carbon fiber braided belt, balsa wood, aircraft skin (heat shrinkable film), various daily necessities can also be modified, such as the thin PET plastic of beverages can be used as a cockpit cover, and the combination of gel pen refill and spring can be used as a simple suspension landing gear ......There are also many kinds of tools. Do other models, what models.

Material? It is possible to make use of thin aluminum cans, plastic bottles, HDPE medicine bottles, hard balsa boards, PVC pipes, tapes, PP plastic sheets for folders. A whole lot, see what you do?

What tools to use to do hand-drawn patterns in the mold.

The brushed pattern on the surface of the mold is a kind of leather grain;

The process principle and process of mold corrosion skin pattern:

Generally, the mold etching adopts anti-corrosion transfer ink, screen printing decorative patterns on the decal paper, and transfers the decorative pattern ink to the mold by the film method, and after drying and trimming, chemical corrosion is carried out to make concave and convex decorative patterns on the mold.

Process flow: base map production, photographic plate making, screen plate making, ink blending, decal paper printing decorative pattern, ink drying, mold pretreatment, decal transfer, drying, trimming, corrosion, inspection, cleaning, rust prevention.

ABS, PC, AS, PS, etc. The following are the requirements for a reasonable selection of injection molds: (I hope it will help you).

1. High corrosion resistanceMany resins and additives have a corrosive effect on the surface of the cavity, which makes the metal on the surface of the cavity dissolve and peel off, the surface condition deteriorates, and the quality of plastic parts deteriorates. Therefore, it is best to use corrosion-resistant steel, or chrome and cymbal nickel plating on the cavity surface.

2. Good wear resistance, the gloss and accuracy of the surface of the injection molded parts are directly related to the wear resistance of the surface of the injection mold cavity, especially when some plastics are added with glass fiber, inorganic fillers and some pigments, they flow together with the plastic melt in the runner and mold cavity, and the friction on the surface of the cavity is very large.

3。Good dimensional stabilityDuring injection molding, the temperature of the injection mold cavity should reach more than 300. For this purpose, it is best to use tool steels that have been properly tempered (heat-treated).

Otherwise, it will cause a change in the microstructure of the material, resulting in a change in the size of the injection mold.

1. A mold is a tool used to make molded items.

2. Molds, various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods. This kind of tool is composed of various parts, and it mainly realizes the processing of the shape of the object through the change of the physical state of the molded material.

3. In addition to the mold itself, the mold also needs the mold base, the mold base, the mold core to lead to the ejection device of the workpiece, etc., and these parts are generally made into a general type. It is known as the "mother of industry".
