Why Choosing the Right Mold Partner Matters: Precision, Reliability, and Global Compatibility

In today’s competitive manufacturing landscape, selecting the right partner for custom plastic and rubber components is more than just a cost decision — it directly impacts product quality, production efficiency, and long-term reliability.

At Rilong, we specialize in high-precision, fully customized mold manufacturing, backed by over 30 years of industry experience. Our goal is not just to deliver molds, but to provide complete, end-to-end solutions that support our customers throughout the entire product lifecycle.


Advanced Tooling Equipment for High-Precision Molds

Precision starts with capability. Our facility is equipped with advanced tooling machinery from globally recognized brands, including:

  • Sodick
  • Charmilles
  • FANUC

Alongside these, we operate a full range of CNC machining centers, EDM systems, and precision grinding equipment.

This allows us to achieve tolerances as tight as 0.005 mm, ensuring:

  • Exceptional dimensional accuracy
  • Consistent part quality
  • Smooth and reliable assembly performance

Even for highly demanding applications, our tooling solutions are designed to meet the highest standards.


Engineering Expertise Built for Global Projects

Our engineering team brings over 20 years of hands-on experience in mold design and manufacturing, with a strong focus on export and transfer-ready tooling.

This expertise enables us to:

  • Understand international mold standards and customer expectations
  • Design molds compatible with overseas injection molding systems
  • Anticipate and prevent common issues during mold transfer

We don’t just build molds — we design them with real-world production environments in mind.


Certified Quality Systems & Process Control

Quality is not an afterthought — it is integrated into every step of our process.

We are certified under:

  • ISO 9001 – Quality Management System
  • ISO 14001 – Environmental Management System
  • IATF 16949 – Automotive Quality Management

In addition, we implement a strict 7S management system to ensure:

  • Operational efficiency
  • Full traceability
  • Consistent process control

These systems form the foundation of our commitment to delivering reliable, high-quality tooling solutions.


In-Process Inspection at Every Critical Stage

At Rilong, quality control doesn’t stop at final inspection — it is built into every stage of production.

With in-house equipment such as:

  • CMM (Coordinate Measuring Machines)
  • VMS (Vision Measuring Systems)
  • Color testing instruments

We perform inspections throughout:

  • Electrode manufacturing
  • Mold component machining
  • Final mold assembly

This approach ensures:

  • Early detection of deviations
  • Stable and repeatable quality
  • Reliable performance, especially for transfer-ready molds

More Than a Supplier — A Long-Term Partner

We believe successful projects are built on strong partnerships.

By combining:

  • Advanced equipment
  • Experienced engineering teams
  • Certified quality systems
  • Deep understanding of global production requirements

We provide not just products, but ongoing technical support and value.
