The chemical industry

Project Background

A leading domestic chemical solvent manufacturer faced critical production challenges. Their semi-automatic bottle blowing line failed to meet the latest explosion-proof safety regulations for chemical workshops. With a single-shift capacity of only 8,000 units of 20L chemical drums, it could not support their annual production target of 150,000 tons of solvents. They urgently needed a professional chemical industry dedicated bottle blowing machine to upgrade their production line.

Tailored Solutions

Hench provided a fully customized ATEX certified explosion-proof PET bottle blowing machine turnkey solution, perfectly adapted to the harsh production environment of chemical plants:

1.Full Explosion-proof Design： Equipped with ATEX and IECEx certified electrical components, meeting Zone 2 explosion-proof requirements for chemical workshops, eliminating safety hazards at the source

2. High-speed Stable Forming：Dual-station mold design enables 20L chemical drum forming cycle in just 45 seconds, increasing single-shift capacity to 28,000 units

3. Corrosion-resistant Upgrade：Custom Teflon-coated molds for producing packaging bottles for highly corrosive chemical raw materials

4. Smart IoT Management：Industry 4.0 MES system enables remote monitoring and fault warning for the automatic chemical drum production line

Project Achievements

1. Safety Compliance：The entire production line passed the national explosion-proof testing center certification and successfully passed the chemical park safety review

2. Productivity Leap：250% increase in production efficiency, fully meeting the enterprise’s 150,000-ton solvent packaging demand

3. Cost Optimization：Preform defect rate reduced from 7.8% to 0.9%, saving over 1.6 million RMB in raw material costs annually

4. Industry Recognition：The project was awarded as the Annual Benchmark Case for Intelligent Upgrading in the Chemical Industry
