PVD (Physical Vapor Deposition) is a high-end surface finishing process widely used in prototyping to achieve mass-production-like appearance and improved wear resistance. This article explains what PVD is, why it suits appearance and functional prototypes, its limitations, and common applications in consumer electronics, automotive interiors, and medical devices.

PEEK CNC machining for functional prototypes with high strength, heat resistance, and dimensional accuracy. Ideal for medical, aerospace, and automotive applications.

CNC machining overcutting can seriously affect part accuracy and lead to costly scrap if not properly controlled. This article explains the most common causes of overcutting, including programming errors, tool deflection, system instability, incorrect tool setting, and tool mismatch. It also provides practical solutions such as program simulation, proper tool length control, regular CNC system maintenance, and improved operator training.

What makes an injection mold perform accurately and efficiently? The answer lies in the seamless collaboration of its eight core systems. Understanding these systems helps optimize mold design, improve product quality, and reduce production costs. Whether you’re developing simple or complex plastic parts, SG PROTO offers tailored mold solutions backed by professional expertise.

SG PROTOTYPE utilizes 3D printing for rapid prototyping of realistic fruit and vegetable models, extending the technology's application to daily life. By selecting resin material for its high accuracy and smooth surface finish, and applying detailed post-processing including manual polishing and custom painting, the achieved prototypes are nearly indistinguishable from real produce.

This article explains how plastic electroplating makes plastic look like metal, using either electroplating (for ABS) or vacuum deposition (for various plastics). SG PROT follows a clean-coat-protect workflow and provides quotes within 24 hours after reviewing 3D files.

Knurling is a specialised finishing process that enhances grip, functionality, and aesthetics of cylindrical components. This article introduces common knurling types—including straight, diagonal, diamond, and crisscross patterns—along with SG Prototype’s machining experience, dimensional allowances, and real application cases. Knurling is widely used for functional validation and appearance evaluation, helping prototypes closely match mass-produced parts and reduce design ri

Flatness defects are a frequent challenge in CNC metal machining, affecting both appearance and dimensional accuracy. This guide explains the key causes—including machine misalignment, material stress, improper clamping, tool wear, and environmental factors—and offers practical solutions such as stress-relief machining, proper fixturing, and optimized cutting parameters. By refining processes and managing internal stress, manufacturers can significantly enhance flatness preci
