Liva's vibration control engineers conducted on‑site surveys and measurements, and customized a high‑deflection damping spring isolation system for the press. After the retrofit, the entire machine runs as steady as flat ground, and the neighboring plant no longer feels any vibration. This real‑world case demonstrates our professional isolation capabilities with tangible results.
**Case Background:** The client is a mold manufacturing company in Kunshan. Its workshop houses a heavy-duty press with a deadweight of 130 tons and a stamping force of 800 tons. The machine's extremely high impact during operation has caused multiple persistent problems: the high-frequency impact has torn and cracked the workshop floor in multiple locations, creating potential foundation safety hazards; vibration energy propagates through walls to adjacent factories, interfering with the machining accuracy of their precision equipment and triggering repeated complaints. The client had previously invested in two rounds of retrofit measures, but the vibration issues remained unresolved, leaving production operations and neighborhood disputes as dual roadblocks.
**The client's previous two vibration isolation solutions both failed, offering only temporary fixes without addressing the root cause:**
**Deep excavation and pouring of a vibration-proof foundation pit**
– This only enhanced the load-bearing capacity of the floor but failed to interrupt the transmission of vibration energy.
**Installation of the press manufacturer's original spring isolators**
– The stiffness parameters did not match the equipment's characteristics, actually exacerbating resonance and making the vibration disturbance to neighbors even worse.
Both solutions consumed significant cost and schedule without delivering results. Following a referral from industry peers, the client reached out to Liva Environmental Technology (LIVA-EP), a company specializing in vibration and noise control.
**Upon receiving the request, Liva's technical team immediately visited the client's facility, implementing a full suite of standardized professional services. Rejecting a "one-size-fits-all" approach to isolation products, they followed a rigorous process:**
**On-site precision vibration measurement – data-driven root cause identification**
The engineering team brought spectrum analyzers to collect comprehensive data, including peak stamping impact values and floor transmission characteristics. This enabled precise identification of vibration frequencies, with all decisions based on actual measurement data rather than empirical guesswork.
**One-on-One Tailored Low-Frequency Damping Spring Isolators**
Integrating the 130-ton equipment deadweight, instantaneous stamping impact forces, and the current condition of the facility's foundation, the team designed a dedicated isolation system specifically for this application, providing complete structural drawings and load calculation reports. The damping and spring stiffness were precisely matched to perfectly suit the high-impact operating conditions of the heavy-duty press.
**On-Site Engineer Guidance for Installation and Commissioning**
Throughout the entire installation process, engineers were present on site to supervise and support, ensuring standardized completion of isolator hoisting, leveling, and securing, thereby preventing any isolation failure caused by improper installation.
**Post-Completion Re-Measurement and Acceptance – Data Visually Demonstrates Isolation Effectiveness**
After installation, vibration levels were re-measured at all test points. The clear before-and-after data comparison provided visible and measurable evidence of the isolation performance, delivering tangible and reliable results to the client.
** Retrofit Results Exceed Expectations – Operation Feels Vibration-Free, Vibration Complaints Completely Resolved**
After the installation of Liva's damping spring isolators, the measured isolation efficiency reached 98%, far exceeding the client's expectations. At full-speed stamping operation, nearly no vibration was felt when standing on the floor around the equipment; the floor surface no longer sustained continuous impact-induced cracking. Vibration energy was completely blocked, with no transmitted vibration reaching the adjacent workshop, allowing their precision machining equipment to resume stable production. The long-standing neighborhood complaints have been entirely eliminated. With no further costly retrofits required, the equipment, foundation, and surrounding production lines are now protected in a single, comprehensive solution.
