Learn how different metal fabrication methods compare in cost, precision, and speed to find the right solution for your custom parts.
Learn how machining, metal conditioning, finishing, and assembly transform basic parts into high-precision components ready for real-world use. Discover how the right secondary process can boost quality, performance, and cost efficiency.
Sheet metal stamping dies are the backbone of precision part production, from brackets to enclosures. In this guide, explore how stamping dies work, the different types used in manufacturing, and how to choose the right die process for your part’s design, tolerance, and volume.
We've curated a list of verified die casting manufacturers in China for 2026, covering aluminium, zinc, and multi-process casting. Compare factory scale, certifications, and best-fit use cases.
See eight Haizol verified metal stamping factories in China with deep draw fine blank and progressive die capacity. Compare their certifications factory sizes and best fit use cases before you source.
Most “top 10 CNC shops in China” lists are written by the companies on them. This guide uses Haizol’s 2026 industry analysis of 456 CNC factories to answer the real questions: which shops to trust for one-offs, what they cost, and how to protect your IP.
This guide covers every major type of machining process used in custom parts production. It splits processes into two categories: conventional (turning, milling, drilling, grinding, broaching) and non-conventional (EDM, laser, waterjet, ultrasonic). Each process is broken down by the tolerances it achieves, the materials it works with, relative cost, and the production volumes it suits best. The guide also clarifies where CNC fits in, since CNC is an automation method, not a machining type. A full comparison table and FAQ section help readers match the right process to their part without needing to dig through multiple sources.
Material selection determines whether a CNC milled part meets its performance requirements, stays within budget, and can be machined to the required tolerance. This guide compares the four major CNC milling material categories: aluminum alloys, stainless steel grades, titanium, and engineering plastics. Each section covers grade-level differences, cost trade-offs, machinability, and which surface finishes are compatible with each material.
Sourcing aerospace parts CNC machining from China requires the same certification, traceability, and inspection standards as any other supply source. This guide covers how to confirm AS9100 Rev D status in the IAQG OASIS database, what constitutes genuine material mill traceability, which tolerance tiers China factories hold on aerospace features, and how to enforce AS9102 First Article Inspection through the purchase order.
