Company Profile:
QINGDAO COSINE Electrical Equipment specializes in supplying various types of insulators and pole line hardware. With rapid development in power construction both in China and abroad, QINGDAO COSINE has become a leading exporter of insulators in China.
Our product range includes polymer insulators from 10KV to 500KV, porcelain insulators from 40KN to 420KN, and a wide variety of pole line hardware. All insulators are produced using modern equipment. For example, our 500KV polymer insulators are manufactured using high-volume injection machines that can produce two units at once. For porcelain insulators, we have imported vacuum pug mills from Germany to ensure quality control from the raw material stage.

Primary Bending Techniques
-
Press Brake Bending:Â Uses a punch and die to create sharp angles or curves, ideal for high-volume production with CNC-controlled accuracy.
-
Roll Bending:Â Shapes metal into smooth curves or cylinders using rotating rollers, common in pipelines, tanks, and architectural elements.
-
Air Bending:Â A versatile method where the sheet is partially pressed into a die, minimizing tooling costs and allowing flexibility for multiple angles.
-
-
Material Adaptations
-
Different metals (e.g., stainless steel, aluminum, copper) require tailored approaches due to varying ductility and springback effects. For example, aluminum may need overbending to compensate for rebound.
-
-
Precision & Tooling
-
CNC press brakes ensure repeatability for tight tolerances (±0.1mm), while specialized dies (e.g., v-dies, gooseneck tools) accommodate unique profiles.
-
-
Applications
-
Widely used in automotive body panels, HVAC ductwork, enclosures for electronics, and structural frameworks in construction.
-
-
Challenges & Solutions
-
Addresses issues like cracking in high-strength alloys (mitigated by heat treatment) or distortion in thin sheets (controlled via incremental bending).
-
-
Innovations
-
Advances include AI-driven bend sequencing, 3D simulation for springback prediction, and hybrid machines combining laser cutting and bending for streamlined workflows.
-
From prototyping to mass production, mastering metal bending ensures efficient, cost-effective fabrication of durable and dimensionally accurate sheet metal parts.
