High-Stability Linear Slide Engineering
Dual-piece split sliding rail structure forms a closed linear movement track, the embedded bright ground wear insert eliminates direct friction between main slide bases, effectively reducing abrasion and sliding jitter during high-frequency reciprocating travel. Built-in mechanical limit stop block precisely controls effective sliding stroke, preventing over-travel collision damage to fixtures or mold cavities. Multi-position threaded mounting holes are distributed on each module, supporting flexible installation on automation equipment frames and mold plates, with tight positional tolerance to ensure consistent sliding parallelism after repeated disassembly.
Integrated thick solid base frame greatly improves anti-impact rigidity, resisting deformation under long-cycle clamping impact and mold clamping pressure to maintain micron-level sliding positioning accuracy.
High Hardness Wear-Resistant Cr12MoV Steel Construction
Cr12MoV cold work steel delivers outstanding performance for high-cycle sliding assemblies:
- High hardness after heat treatment, excellent anti-abrasion capacity, suitable for long-term friction contact with glass fiber reinforced plastic and metal workpieces
- High compressive strength and impact toughness, no cracking or indentation under frequent reciprocating impact loads
- Good grindability to achieve ultra-smooth sliding rail surface, lowering friction resistance without frequent lubrication maintenance
- Black gas nitriding surface treatment further boosts surface hardness and anti-rust performance, adapting to humid workshop environments with cutting fluid splash Ideal for heavy-load automation clamping stations and high-volume injection mold side core pulling applications.
