Spring is a beautiful season, Spring is a planting and planning season, many exhibitions are held in every spring!
In 2024 Spring, EJS presented at ChinaPlas in Shanghai and NPE in Orlando.
Because of Covid, last time we had ChinaPlas Shanghai was in 2018, while last NPE was also in 2018.
It was a LONG time ago since last meeting, everyone were eager to meet together again.
We were happy that we were able to talk with our old customers again face to face at the show, it was even better to see our customers growing steadily all these years!
No doubt, Quality Stands!
If you haven't got a chance to meet our people at the booth, please contact us to schedule another appointment, we could meet at our factory!
You are always welcome and invited as well as encouraged to walk in our workshops from screws to barrels---
We are not mean to show you what screw barrels we are producing day in and day out since day one.
We are not shy to show how we produce 30000 screw barrels each year for our customers nationally and internationally.



Founded in 1992, our factory grew out from a small workshop of conical twin screw barrel production. Thanks to all dedicated employees and loyal customers, our factory is now running by 400 full-time employees with 21 workshops covered in an area of 40 000m2, with a range of screw barrels are produced including Extruder Screw Barrel, Injection Moulding Screw Barrel, Rubber Screw Barrel, Twin Screw Barrel and Extruder Parts.
From the very beginning of establishment, E.J.S is designed to produce high quality screw barrel, by using Top-Class steel 38CrMoAla, 40Cr, 42CrMo which are most popular for Chinese Market. For processing various application and meeting different needs from customers all over the world, nowadays we have more steels for option, 1.8550(34CrAlNi7), 1.8519(31CrMoV9), D2, Hastelloy, SKD61, SKD11 etc. We believe good raw material is the grounding and footstone to make a good job.
Details matter, this is especially true for screw barrels. The precision and accuracy of product dimensions separate one factory from another.
JinTang Island, where our factory is located, also called " Island of Screws", has hundreds of companies making screws and barrels, small and big, old and new, with about 30000 people working in this business. If you want to cheaper prices, keep asking.
If quality is critical, you have much less options unfortunately. The rule" Every penny counts" works great here.
If quality is your top priority, E.J.S is your great option.
Most of our screws and barrels are produced for other brands of extruder machines and injection molding machines, you will not know it is from us.
