Engineered Capabilities That De-Risk Your Supply Chain.
Four pillars of manufacturing integrity — from custom R&D to field diagnostics.

Deep R&D & Flexible OEM Customization
Allocating over $1.4M annually to raw R&D with a library of nearly 3,000 active molds (lengths spanning 550mm to 12,000mm). We rapidly engineer custom tooling configurations designed for your exact operating hazards — whether fighting heavy oil contamination or volatile thermal spikes.

Source Integrity & Vertically Integrated Supply
We strictly refuse out-sourced rubber compounds. Utilizing our standalone proprietary automatic compounding center alongside 12 semi-automated structural molding lines, we maintain absolute ownership of the process from raw polymer to boxed cargo — guaranteeing strict bulk shipments within 15–20 days.

Rigorous Quality Management Infrastructure
Certified as a Class-A Quality Inspection Institution for Petroleum & Chemical Industries. From raw rubber Mooney viscosity testing to 13 rounds of 120°C thermal fatigue trials lasting 500 hours without a single micro-crack, we implement mandatory 100% batch sample checking before logistics clearance.

Dedicated Engineering Selection & Alignment Field Support
We provide upfront pre-sale drive selection math modeling, lifecycle calculations, component failure diagnostics, and rigorous dynamometer bench testing to ensure precise physical fitment before your equipment ever rolls off assembly lines.
Quality Is Systemic, Not Accidental.
Four precision stages — from raw compound to digital warehousing.

Raw Compound & Internal Mixing
100% inspection on arriving raw polymers. We combine premium imported Aramid (Kevlar®) tensile cords with high-grade EPDM/HNBR bases, utilizing automated internal mixers for molecular-level distribution.

Structural Shaping & Vulcanization
Deploying a high-pressure integrated co-vulcanization technique. Micro-processors tightly lock down cure temperatures and pressures, ensuring the multi-layer composition permanently resists delamination or tension stretching.

Precision Slitting & Profile Grinding
Utilizing single-blade micro-slitting machinery. This ensures uniform cross-sectional friction indexes across the raw belt profiles, driving silent operation and removing vibration anomalies.

Digital Inventory & Smart Warehousing
Finished stocks sit in 4-tier structural matrix storage zones. Fully managed under custom integrated enterprise resource planning (ERP) tracking networks to secure absolute dispatch accuracy.
Behind the Machinery Stands an Unyielding Engineering Culture.

‘Uncompromising focus on supreme quality’ is not an empty slogan at HEIYI. It is the operating directive for our 300+ career manufacturing staff and 20+ specialized application engineers. From raw formula chemistry to field stress audits, we lock human craftsmanship into every single belt profile to safeguard your operational continuity.

Direct Answers. Zero Friction.
Neutralizing transactional doubts before you reach the conversion zone.

Standard custom bulk fulfillment parameters run between 15 to 20 days. We maintain extensive raw stock compounds and a disciplined rolling manufacturing schedule. Critical line-down emergencies can trigger priority production sequencing to protect customer operations.
Yes. We offer standard private-label branding (OEM) as well as advanced engineering support. Leveraging our library of nearly 3,000 active mold geometries and our dedicated R&D lab, our application specialists can quickly generate custom belt configurations from your physical drawings or machine operational data.
Every shipment is protected under our comprehensive industrial warranty program. In the rare event of a performance discrepancy, our dedicated technical team cross-references batch records and runs comparative dynamometer tests. If required, we can deploy application specialists to diagnose field assembly tracking issues firsthand.
Stop Settling for Supply Chain Uncertainty.
Formally designated as a ‘Hebei Provincial Green Factory,’ we maintain strict control parameters over exhaust emissions and industrial scrap. By manufacturing high-durability, long-lifecycle belt profiles, we reduce global rubber waste, aligning industrial throughput with environmental sustainability.
