Understanding Injection Molding Terms: What Do 1*2 and 1+1 Mean?
Jan 21,2025
If you're in the manufacturing industry, you've probably heard of injection molding. It's a popular process for producing plastic parts in large quantities. However, it can also be a complex process with many technical terms to understand. Like "1*2" or "1+1”, we call it “1 out 2” and “1 plus 1” But what does it mean?
This blog aims to clarify what injection molding is, explain what 1*2 and 1+1 mean, and delve into other related terms.
What is Injection Molding?
Injection molding is a manufacturing process used to produce plastic parts by injecting molten material into a mold. The cavity within the mold is the space into which the molten plastic is injected and is ultimately what shapes the final product.
What do 1*2 and 1+1 mean in injection molding?
The terms 1*2 and 1+1 may seem to have the same result in math; however, they represent different configurations of mold cavities:
- 1*2: This means that one mold contains two identical cavities, allowing for the simultaneous production of two parts.
- 1+1: This refers to a mold that has two different cavities, but produces two different parts at the same time. Most commonly used for production parts L/R
This distinction is crucial in injection production as it defines the efficiency and versatility of the manufacturing process.
And Test!
What do 1+1+1,1+1+1+1*2, 1+2+2 and 2+2+2 mean?
Utilizing multi-cavity molds in injection molding can present both advantages and disadvantages. The design of the mold needs to consider the product parameters, quantity, mold-making cost, production cost, and many other factors.
That's why it's important to work with an experienced engineering team that can provide you with the most cost-effective advice and services.
