Executive Summary: A Foundation of Strength in Undercarriage Manufacturing

This document presents the corporate and technical profile of HELI MACHINERY MANUFACTURING CO., LTD., operating under the brand CQCTRACK. As a vertically integrated manufacturer with over two decades of specialization, HELI has established itself as a leader in the design and production of heavy-duty crawler excavator undercarriage components. Rooted in the industrial hub of Quanzhou, China—a region renowned for its concentration of mechanical manufacturing—HELI serves the global market as a proficient OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) partner. Our core competence lies in transforming raw forged steel into precision-engineered, high-durability track systems, underpinned by a philosophy of relentless process control and application-driven engineering.

1. Corporate Identity & Strategic Positioning

1.1 Company Evolution & Market Position
Founded in the late 1990s, HELI MACHINERY has grown in parallel with China’s construction machinery boom. From a specialized parts workshop, we have systematically evolved into one of the top three undercarriage component manufacturers in the Quanzhou region, a key supply cluster for global earthmoving equipment. Our growth is attributed to a steadfast focus on the undercarriage niche, investing in advanced manufacturing assets and cultivating deep technical expertise in metallurgy and tribology specific to track systems.

1.2 Brand Promise: CQCTRACK
The CQCTRACK brand symbolizes our dedication to the Crawler, Quality, and Commitment that form the foundation of every machine. It represents a product line built for resilience, engineered to endure the most abrasive and high-impact environments in mining, quarrying, and major infrastructure projects.

1.3 OEM & ODM Service Model

• OEM Manufacturing: We produce components to exact client specifications, drawings, and quality standards. Our factory is adept at seamless integration into global supply chains, providing reliable, volume production of rollers, idlers, sprockets, and track links.
• ODM Engineering: Leveraging our extensive field experience, we collaborate with clients to develop, design, and validate improved or fully customized undercarriage solutions. Our engineering team proactively addresses common failure modes, offering value-optimized designs that enhance performance and total cost of ownership (TCO).

2. Core Manufacturing Capabilities & Technological Infrastructure

HELI’s manufacturing prowess is built on complete vertical integration and controlled, sequential processes.

2.1 Integrated Production Workflow:

1. In-House Forging & Forging Alliance: We utilize premium 52Mn, 55Mn, and 40CrNiMo alloy steels. Through strategic control of forging, we ensure optimal grain flow and material density in component blanks, which is fundamental for impact strength and fatigue life.
2. CNC Machining Centers: A battery of modern CNC lathes, milling machines, and drilling centers performs rough and finish machining, ensuring dimensional accuracy to ISO 2768-mK standards and consistent interchangeability.
3. Advanced Heat Treatment Lines: Our dedicated facility features computer-controlled induction hardening and tempering furnaces. We specialize in achieving deep, uniform case hardness (58-63 HRC) with a tough, ductile core, a critical factor for component longevity.
4. Precision Grinding & Finishing: Critical wear surfaces (e.g., roller races, sprocket tooth profiles, shaft journals) undergo precision grinding to achieve superior surface finish and exact tolerances.
5. Automated Assembly & Sealing: A clean, organized assembly line ensures proper installation of seals, bearings, and lubricants. We employ multi-labyrinth seal configurations with high-grade nitrile or Viton® lip seals as standard.
6. Surface Protection: Components are shot-peened for stress relief and coated with high-bond, corrosion-resistant primers and paints.

2.2 Quality Assurance & Laboratory

• Material Analysis: Spectrometer for raw material chemical verification.
• Hardness & Depth Testing: Rockwell and Brinell testers, with macro-etching for case depth validation.
• Non-Destructive Testing (NDT): Magnetic particle and ultrasonic inspection for critical components to detect subsurface flaws.
• Dimensional Inspection: CMM (Coordinate Measuring Machine) and precision gauges for 100% final inspection of key parameters.
• Performance Testing: Custom-built rigs for rotational torque, seal pressure, and simulated load cycle testing on sampled assemblies.

3. Product Portfolio & Engineering Focus

HELI manufactures a comprehensive range of undercarriage wear parts, with engineering enhancements tailored for severe-duty applications.

3.1 Primary Product Lines:

• Track Rollers (Bottom & Top): Forged bodies with deep-hardened rims and flanges. Options include lubricated (LGP) and non-lubricated (NGP) designs.
• Carrier Rollers & Idlers: Built with robust sealed bearings or bushings, designed to manage high radial and axial loads.
• Track Sprockets (Drive Wheels): Segment or solid designs, with precisely cut, hardened teeth for optimal engagement and reduced track chain wear.
• Track Chains & Bushings: High-alloy steel links, induction-hardened and precision-drilled. Bushings are carburized for maximum wear resistance.
• Track Shoes: Single, double, and triple-grouser designs for various ground conditions.
• Eight forged bucket teeth production lines and a newly built factory of over 10,000 square meters.

3.2 Engineering Design Philosophy:
Our ODM development follows a ”Failure-Mode-Driven” approach:

• Problem Identification: Analyze returned parts from the field to identify root causes (e.g., seal lip wear-out, spalling, abnormal flange wear).
• Solution Integration: Redesign specific features—such as seal groove geometry, grease cavity volume, or flange profile—to mitigate these failures.
• Validation: Prototype testing ensures the design improvement delivers measurable life extension before entering mass production.

4. Quality Management & Certifications

• System Certification: Our operations are governed by an ISO 9001:2015 certified Quality Management System, ensuring process discipline and continuous improvement.
• Traceability: Full material and process traceability from forging to final assembly is maintained for every production batch.
• Standards Compliance: Products are engineered to meet or exceed international standards such as ISO 7452 (Test methods for track rollers) and other relevant OEM-equivalent specifications.

5. Global Supply Chain & Customer Value Proposition

5.1 Supply Chain Reliability:

• Strategic Location: Based in Quanzhou with efficient access to major ports (Xiamen, Quanzhou), facilitating reliable global logistics.
• Inventory Management: Support for both bulk orders and flexible JIT (Just-In-Time) delivery programs to align with client procurement cycles.
• Packaging: Export-standard, weather-resistant packaging on solid wooden pallets to ensure product integrity during transit.

5.2 Value Delivered to Partners:

• Superior Total Cost of Ownership (TCO): Our components offer extended service life through superior materials and hardening, reducing machine downtime and frequency of replacement.
• Technical Partnership: We engage as a problem-solving partner, offering engineering support for specific application challenges.
• Supply Chain Simplification: As a factory-direct source with full manufacturing control, we provide consistency, transparency, and competitive scalability.
