About Us

Small Workshop,
Serious Precision.

Based in Harbin — home to China's top aerospace and engineering universities — we've spent a decade machining precision parts for research projects that push boundaries.

Who We Are

We're not a big factory. We're a small, focused machining shop that specializes in what large factories don't want to bother with: one-off parts, small batches, tight tolerances, and tricky geometries.

Over the years, we've become a go-to partner for research groups at Harbin Institute of Technology, Harbin Engineering University, and several defense research institutes. They come to us because we understand their drawings, we ask the right questions, and we deliver parts that work — not just parts that look close enough.

Beyond machining, we also do process optimization, structural design assistance, and full-stack R&D through our Sancai Maker team. And we're developing our own pulsed laser products under the PricLaser brand. Small team, real capabilities.

Our Journey

Ten years of machining parts for projects that matter.

2014

Workshop Started

Set up a small CNC shop in Harbin's Pingfang District. Started with 2 machining centers, taking on jobs from university labs.

2016

Steady Partnerships Formed

Began regular cooperation with Institute 703 and Xinguang Photonics. Added wire EDM to handle tougher jobs.

2018

5-Axis Capability

Added a 5-axis machining center. More complex parts, fewer setups, better accuracy on tricky geometries.

2020

Growing the Team

Team grew to around 20. Small precision parts consistently hitting 10μm tolerance. More process optimization work coming in from researchers.

2022

Sancai Maker Launched

Started a dedicated R&D team — mechanical, electronics, software. Helping clients go beyond just machining, into full product development.

2023

PricLaser Started

Began developing high-power pulsed laser systems for long-range LiDAR applications. Still in R&D, but making progress.

2024

Going Online

Launched our website to reach researchers and engineers worldwide. Started accepting international orders.

2025

Expanding Capabilities

Upgraded quality inspection with precision measuring instruments. PricLaser entered prototype testing phase.

2026

Laser Product Milestone

PricLaser completes field validation for long-range LiDAR. Actively seeking OEM partnerships for pulsed laser integration.

Leadership Team

Each brand is led by someone who knows the work firsthand.
