Send STEP/IGES/PDF and key requirements (material, tolerance, finish, quantity).
We confirm manufacturability and share a fast quote with lead time.
Production starts after approval. In-process checks ensure stable quality.
Final inspection, protective packaging, and safe shipping. Reports available on request.
At MinHe, every batch of parts follows a clear and traceable quality workflow. From incoming material verification and first-article checks to in-process inspection and final release, we document and review each step to make sure the parts you receive are consistent and reliable.
We set inspection checkpoints at incoming, first-article, in-process, and final stages. Critical dimensions, appearance, and functional features are checked against drawings and specifications, and any non-conformities are isolated and fed back into corrective actions.
Our quality lab is equipped with CMMs, optical projectors, hardness testers, and other measuring tools. Dedicated inspectors handle daily measurements and data recording, and custom gauges or inspection plans can be set up for complex or tight-tolerance parts.
We can provide FAI reports, batch inspection records, and other documentation on request. All production and inspection activities run under an ISO-based quality management system with full traceability to support your internal audits and supplier management.

Geometric dimensioning and tolerancing, usually shortened to GD&T, is a symbolic language for defining geometry on engineering drawings. It covers more than size, spelling out the allowable form, orientation, location, and runout of each feature so a designer, a machinist, and an inspector read the same requirement. Conventional plus/minus dimensions leave real geometry open to…
A transition fit is an engineering fit in which the shaft and hole tolerance zones overlap, so the assembled parts may end up with a small clearance or a slight interference depending on the actual machined sizes. It is used when a component must be positioned precisely but still be assembled and disassembled without force, such as locating pins, gear hubs, and bearing assemblies. On drawings, it is specified with ISO codes such as H7/k6. Choose a transition fit for precision location with light-force assembly; use an interference fit for permanent high-load joints and a clearance fit for free movement.
Every dimension on a drawing needs a tolerance, and the type you choose matters as much as the number. A bilateral tolerance like 10.00 ±0.05 allows variation on both sides of nominal. A unilateral tolerance like 10.00 +0.05/-0.00 allows it on one side only. The choice is not a style preference: it controls whether a…
CNC machined parts often retain cutting fluids, oil, and metal chips on their surfaces after turning, milling, or five-axis machining. If these residues are not thoroughly removed, they can affect dimensional inspection and assembly, and may also lead to rust, stains, or customer acceptance issues during transportation. This article explains the standard cleaning process for CNC machined parts, cleaning considerations for aluminum, steel, and copper, common cleaning mistakes, and how manufacturers integrate cleaning into their quality control process.

This article explains the basic concept of CNC text milling, the machining process, and how CAM converts text into G-code. It also discusses how font selection, tool types, material properties, and design rules affect the clarity, durability, and machining cost of milled text.
Choosing between 3-axis, 4-axis, and 5-axis machining is not simply about using more axes. The key is whether the part features require better tool angles and fewer setups. This article compares the three CNC machining configurations from the perspectives of tool access, workholding setup, part complexity, programming difficulty, and total machining cost, helping readers make a practical process selection.
