Certified Quality & Management Systems

Tonghe runs production under ISO9001 quality management and supports CE requirements for export projects. Quality checks are built into daily work, from incoming material to final testing.


Production Data & Traceability

Production Data & Traceability

Key parameters, assembly records and test results are recorded by machine. This helps us find issues early, keep batches consistent and support customers during installation and after-sales service.

cleaner production methods

We manage dust, noise, oil and packing waste through process rules and daily control. Machine design also focuses on stable forming and less scrap, so customers waste less material during production.

Our Sustainability Policies

Energy & Resource Management

We improve efficiency by matching motors, hydraulics and control systems to the real load, not by oversizing every part.

Environmental Compliance

Production follows applicable environmental and customer requirements, with clear control standards for key processes.

Employee Safety & Health

We reduce operational risk through training, protective measures and clear work instructions on the factory floor.

Long-term Manufacturing Stability

Sustainability is not a slogan. It is stable equipment, repeatable quality and support that customers can plan around.
