Choosing the right plastic welding equipment partner means choosing reliability, expertise, and a manufacturer that genuinely understands your production goals.
From R&D design through to final production and after-sales support — everything happens under one 7,000 m² roof in Zhejiang, China. This integration eliminates supply chain risk, reduces lead times, and gives you a single accountable point of contact for your entire project.
Our 6 granted utility model patents are proof of our engineering depth. We don't just build machines — we invent better ones.
Standard machines don't fit every production line. We specialize in designing and building non-standard, purpose-built equipment tailored precisely to your application requirements.
Our machines deliver consistent, repeatable weld performance meeting the most demanding industry standards — ensuring your production runs smoothly and profitably.
Our experienced technical team provides responsive, thorough after-sales support — from installation guidance to troubleshooting — so your production never stops.
Our in-house production capabilities and efficient workflow allow us to deliver custom machines faster than most competitors, keeping your project timelines on track.
Our customers' success is the most meaningful measure of our work. Here's what manufacturers around the world say about partnering with Zhejiang Heping Mechanical Equipment Co., Ltd.
The custom ultrasonic welding machine Heping designed for our automotive component line exceeded our expectations. The weld strength is consistent, the cycle time is faster than our previous supplier, and their after-sales team resolved our setup questions within 24 hours. Highly recommended for any manufacturer needing a reliable plastic welding partner.
We've been sourcing plastic welding equipment from Heping Mechanical for three years. Their ability to customize non-standard machines to our specific mold dimensions is unmatched.
