📆 Time: October 16-18, 2025📍 Location: Foshan · Tan zhou International Convention and Exhibition center📌 Booth number: 6-007Company ProfileThe design of BBK-JINGBA nitrogen gas springs can meet customers' expectations for product reliability, safety, service life and modern fashion concepts. The design, production and testing of BBK-JINGBA nitrogen gas springs all comply with the European pressure equipment standard (97/23/EC).The Pressure Equipment Standard (PED) has replaced all previous European legislation that was used to regulate the design, production and testing of pressure vessels. The production of BBK-JINGBA brand springs relies on the latest production processes, skilled technical engineers and precision mechanical equipment located in our modern facilities at BBKDVP. As the designer and manufacturer of BBK-JINGBA nitrogen gas springs certified by the European Union for high-pressure vessels, BBKDVP, in 2008, gathered its high-quality R&D personnel and was the f...

Have you ever machined threads on the rod parts of BG450 series and all series nitrogen gas springs for the convenience of your drawings? recently BBK-JINGBA Beibeikang Technology We have received feedback from many customers that in order to install fish eye fixation on the rod, they casually threaded the piston rod, feeling that it was only a small modification and did not affect its use. But as a practitioner who has been deeply involved in mold nitrogen springs for many years,Today, a serious reminder must be given: all Mold nitrogen spring (including BG450 series), it is strictly prohibited to machine threads on the piston rod by oneself! Especially in 2026, as the mold industry transitions towards precision and high-end, there is an increasing demand for equipment safety and product accuracy. This seemingly effortless violation of regulations can result in cost losses and production delays, or even safety accidents. It is truly not worth the loss. Firs...

I. Common Industry Questions + Core Answers1. How to choose the right gas spring model? 3 Core Steps: ① Calculate the force (actual demand + 15%-20% safety margin); ② Select the stroke (working stroke + 5-10mm reserve, do not press to the limit stroke); ③ Match the pressure ratio (1.2-1.4 for simple processes, 1.5-2.0 for deep forming), and select according to the installation space and working conditions. 2. Working Principle of Nitrogen Spring Using high-purity and high-pressure nitrogen as the energy storage medium, it stores energy by compression during mold clamping and rebounds by expansion during mold opening. It has a compact structure and strong elasticity, replacing traditional springs and simplifying the mold structure. 3. Explanation of Force-Stroke Curve Initial force (F₁) is the basic elastic force when fully extended, and terminal force (F₂) is the maximum elastic force at the rated stroke, with pressure ratio K=F₂/F₁; the longer the stroke, the steadily increasi...
