EVA injection molding technology is an important carrier of the core concept that “materials are the prerequisite for product success”. As an innovative company with 15 years of experience in polymer materials, BOOLING has witnessed how EVA has evolved from an ordinary plastic material to a key material that has changed the rules of the game in many industries. By adjusting the ratio of ethylene and vinyl acetate, we optimize the material’s hardness, flexibility, elasticity, and other properties to meet the application needs of customers’ different products.
Advantages of EVA injection molding:
- Good elasticity and toughness
- Lightweight production
- Reduce impact force
- Excellent product surface quality

The molding effect of EVA materials is the most groundbreaking performance. In the severe cold environment of -30℃, our special EVA formula can still maintain excellent flexibility. This breakthrough completely solves the industry problem of traditional materials becoming brittle in winter. Last winter, the low-temperature EVA sole material we developed for a well-known sports brand helped increase its product sales in the Russian market by 35%.
“Material innovation is not a closed-door development,” emphasized our chief materials scientist, Engineer Li, “but it must be deeply integrated with actual application scenarios.” It is based on this concept that we have developed an EVA formula with an energy rebound rate of up to 68%, while maintaining excellent shock absorption performance. This allows our sports shoe customers to reduce material usage by 15% while improving product performance.
EVA Injection Molding Process
The control of parameters by engineers directly determines the quality and effect of the final EVA injection molding product. Booling obtained the best processing parameters through continuous adjustment and optimization.

Injection Pressure | 30~50MPa | Packaging Pressure | 10~20MPa |
Injection Time | 1~3s | Cooling Time | 30~60s |
The Particularity of EVA Injection Molding
Unlike other plastic materials, EVA material has excellent flexibility and elasticity, which can meet the different product requirements of the injection molding market. It has excellent flexibility and can provide users with good touch and comfort. EVA material can maintain good physical properties and will not become brittle or break in low temperature environments, ensuring its service life. This material has a low processing temperature and a low melting point, and excessive temperatures may cause it to carbonize or decompose.
In Booling’s production workshop, each injection molding machine is equipped with our intelligent control system. “Temperature control of ±1℃ and pressure fluctuations not exceeding 0.5MPa are our basic standards,” said Manager Zhang, the production supervisor. This extreme pursuit of process parameters has enabled our EVA products to reach the industry’s top level in terms of dimensional stability and surface finish. We are particularly proud of the fast color change system. Through the unique screw design and cleaning process, we can complete the color change within 20 minutes, which makes small batch customized production efficient and economical. Last year, we completed the production of limited edition soles in 12 colors for an emerging fashion brand. Each batch was only 500 pairs, but we achieved the same quality standards as mass production.
Application of EVA Injection Molding
In the field of sporting goods, we developed a gradient density EVA midsole for an international brand, which achieved the dual functions of high rebound in the forefoot and shock absorption in the heel through a single injection molding. After the product was launched on the market, customers reported that the wearing comfort increased by 42% and the return rate decreased by 28%. Due to the special properties of the material, EVA injection molded products have a wide range of applications in the market.
- Shoe materials
EVA injection molding is often used in the production of soles. While providing a comfortable feel, it also provides cushioning performance, reduces the overall weight of the shoe material, and provides shock absorption.
- Toys
EVA is non-toxic and is often used to make children’s toys, providing a good touch and play experience.
- Electronic equipment
It is used to make the shell of electronic equipment, which protects the electronic equipment while meeting the personalized needs of users and consumers.
- Sporting goods
It is used to make products such as yoga mats and sound insulation mats to reduce noise and provide shock absorption.
