How can we control injection mold processing costs ？ plastic parts production

 

 

Some applications require mold steel with high hardness and high wear resistance to enhance parting line durability, while others require mold steel with higher toughness to resist mechanical fatigue. Therefore, the material selection, mold process, and factory management before injection mold production all affect injection mold processing costs. So, how can we control injection mold processing costs during production?

To summarize, here are three points:

 

1. Steel Selection

 

Some applications require mold steel with high hardness and high wear resistance to enhance parting line durability, while others require mold steel with higher toughness to resist mechanical fatigue. Generally speaking, steel with higher hardness and wear resistance is more brittle. In almost all cases, tougher steel has reduced resistance to steel-to-steel abrasion (adhesion abrasion) and abrasion by glass fiber or mineral-filled resins. Moldmakers can choose to use stainless steel to mold resins that are corrosive to most other steels.

 

Carefully selecting and designing a well-designed injection mold before production is the most fundamental way to reduce costs. Different mold designs have varying requirements for product materials, naturally resulting in both advantages and disadvantages. Excellent molds have a high yield rate, generate less waste, and naturally lower production costs.

 

2. Reasonable Processing Technology

 

The same product, when produced using different processing technologies, requires different raw materials of varying quality and quantity. Based on the product's specific requirements, while still meeting quality requirements, improving the processing technology can reduce production costs.

3. Scientific and Reasonable Management Model

 

During the production process, adopt a scientific and reasonable management approach. Strengthen cost accounting and enhance management across all aspects of production, supply, sales, and finance. Break down each cost item—raw materials, auxiliary materials, fuel, power, wages, manufacturing costs, administrative expenses—into the unit product cost, manage them in a rational and standardized manner, and strictly prohibit waste.

 

By reducing unnecessary waste at every stage, companies can achieve the goal of rationally storing and using materials, reducing costs, and improving efficiency. This ensures reasonable production needs while reducing capital tie-up and waste.
