OUR MANUFACTURING STORY See Inside SUNLIT
Company Timeline

Our Development Journey

From CNC cutting tool distribution to precision industrial component manufacturing.

Started in CNC Cutting Tools Distribution

Our founder, Mark, started the business in Chang’an Hardware City, Dongguan, supplying imported CNC cutting tools to local manufacturers and building long-term relationships with industrial customers.

Authorized Distributor for Japanese & Korean Brands

Through strong technical support and customer service, the company became an authorized distributor for selected Japanese and Korean cutting tool brands in South China.

Acquired HSS M42 Tool Manufacturing Facility

We acquired a high-speed steel cutting tool factory originally operated by a Taiwanese company, including its experienced engineering team and production equipment, laying the foundation for our own manufacturing capabilities.

Shenzhen Sunlit Tools Co., Ltd. Established

SZSUNLIT was established to expand into international markets, providing OEM and ODM manufacturing services for global customers.

Yanling Production Base Established

To improve manufacturing efficiency and production capacity, we established our Yanling production base in Hunan. High-speed steel cutting tool manufacturing was transferred there, while Dongguan continued producing carbide cutting tools.

Manufacturing Capacity Expanded

Additional CNC grinding equipment was introduced to expand production capacity. Standard solid carbide cutting tool manufacturing was transferred to the Hunan production base, while the Dongguan facility focused on high-precision custom carbide tooling and OEM engineering projects.

Pelletizing Knife Manufacturing Factory Established

To support the polymer processing industry, we established a dedicated manufacturing factory for pelletizing knives and precision pelletizing components, including ceramic bedknives, carbide bedknives, rotor blades and OEM-compatible pelletizing parts.

Miniature Magnetic Drive Pump Manufacturing Factory Established

We established a dedicated manufacturing factory for miniature magnetic drive pumps, expanding our manufacturing capabilities from precision cutting components to precision fluid handling solutions.

QUALITY ASSURANCE

Quality Throughout —
Not Just at the End

Quality control is integrated throughout our manufacturing process, from incoming materials to final functional verification.

01

Raw Material Inspection

Incoming material verification against specifications before production begins.

02

Precision Machining & Grinding

CNC grinding with tolerances down to ±0.002 mm and controlled geometry.

03

Dimensional & Edge Inspection

CMM measurement and microscopy for dimensional and cutting-edge verification.

04

Functional Verification

Application-specific functional checks are performed before final release.
