In the precision injection molding industry, each advancement comes with new challenges. This year, DAYIN Plastic Products Co., Ltd. has identified a significant issue facing the industry: the rising cost of injection molding. Below are some primary factors contributing to the increase in injection costs: Increase in Labor Costs In the Pearl River Delta region, rising labor costs have become a notable issue. Particularly in Shenzhen, the minimum wage has increased almost annually. Although the wages of injection technicians are generally above the minimum wage, employee salaries must be adjusted accordingly as the minimum wage rises. Additionally, the difficulty in recruiting workers has forced companies to revise their pay structures, resulting in a continual increase in labor costs, a common trend in the injection molding industry in recent years. Rising Raw Material Prices Due to the impact of oil price fluctuations on plastic production, the increase in raw material prices has directly led to higher injection molding costs. In the second half of 2016, the price of various materials rose across the board due to the increase in basic material costs, with some materials experiencing price hikes exceeding 20%. Although prices slightly decreased after the new year, overall costs remain higher than previous levels. 
Increase in Auxiliary Material Costs A wide variety of auxiliary materials are used in injection molding production, including paper, protective films, lubricants, and various mechanical components. The prices of these materials have also risen significantly, with paper and protective films seeing price increases of over 60%. Due to the relatively high labor demand associated with these materials, their prices have experienced notable growth, and other high-cost components have become common issues as well.

The Cost Anatomy of a Precision Mold
Precision mold quotes vary widely because the cost anatomy varies. The anatomy, layer by layer:
| Cost layer | What drives it | Where buyers can move it |
|---|---|---|
| Design and simulation | Complexity, gate studies | Complete data packets cut iterations |
| Steel and standard parts | Grade, size, delivery time | Honest volume forecasts |
| Machining hours | Features, tolerances, textures | Under-specified drawings resurface here |
| Sampling and correction | First-shot surprises | Upfront simulation, disciplined DFM |
The sampling row is the anatomy’s wildcard: tools priced without adequate simulation budget their surprises into correction loops, and buyers comparing quotes are often comparing different assumptions about who pays for those loops. The machining row hides the mirror image of the tolerance discussion — every over-tight specification is machining hours priced into steel that never needed them. Buyers who understand the anatomy also negotiate the right thing: the steel layer has thin margins and little slack, while the sampling layer is where honest simulation money saves dishonest correction money three times over. The steel-grade questions are in mold material properties, and the validation sequence in sample requirements. Reference: tooling economics and scale effects.
