Which type of steel is more suitable for injection moldsS136 or Cr12MoV
一, What is S136 Mold Steel like
S136 is a high-quality stainless steel that is often used in high-end injection molds, especially in industries where the look of the product is very important.
1. Very good at resisting rust
S136 has a lot of chromium in it and is very good at stopping rust. It is good for making the following plastic products:
medical goods made of PVC plastic
plastic that is safe for food
Things made in wet places
This function can help lower the cost of repairs caused by injection molds corrosion.
二, Great polishing ability
One of the best things about S136 is that it polishes mirrors very well, which makes it good for production:
clear product
Parts for optics
Parts with a high gloss finish
S136 is a popular choice for many high-end electronic equipment shell molds.
3.The mold is quite stable.
S136 can usually reach HRC48-52 hardness after heat treatment. It also stays stable in size and lasts longer.
4. Better quality of the product
Using S136 molds makes it easier to get good surface effects on products and cut down on defects.
二,What makes Cr12MoV Mold Steel special
Cr12MoV is a tool steel with a lot of carbon and chromium. Its main benefits are that it is very resistant to wear and is not too expensive. Many industrial molds use it a lot.
1. Very resistant to wear
Cr12MoV has a lot of carbon and chromium in it, which makes it very hard and resistant to wear. This makes it useful for making:
Plastic goods made from glass fiber
Products made with engineering plastic
Big parts for factories
Works great in production settings where things get a lot of wear and tear.
2. More ways to save money
Cr12MoV is less expensive than S136 and is good for:
Projects that are sensitive to cost
Molds for products in the middle to low price range
Molds for large-scale structures
3.Strong enough for heavy-duty production
Cr12MoV can handle a lot of pressure and doesn't become bent easily when it's made at a high frequency.
But Cr12MoV also has several problems:
Not very good at preventing corrosion
The polishing effect isn't as strong as S136.
Not good for things that are very shiny or clear
三, A comparison of how well S136 and Cr12MoV work Project S136 Cr12MoV
Very good for resisting rust, average
Average polishing performance (like a mirror)
extremely good wear resistance, extremely good
Molds last a long time
Cost that is higher and lower
well for pieces that are see-through, look well, are used in industry, or are part of the structure of a product
四,Ideas for different situations in which to use it
If your product is one of the following sorts, you should choose S136:
Plastic things that are clear
Products with a high gloss finish
Plastics that are safe for food or medical use
Production environment with strict rules for stopping mold from rusting
Cr12MoV may be a better choice for your product if it meets the following conditions:
Parts made of plastic for industry
Made of fiberglass
Not very picky about looks
Making a lot of things with a small budget
五,What mold makers usually do in real life
Many skilled mold factories don't only utilize one type of steel; they use a mix of steels, like this:
S136 is used in the mold core to make sure the product is of good quality.
Use Cr12MoV for the mold frame or portion of the structure to save money.
This method can help find a better balance between cost and performance.
