Bronze Guide Sleeves For Mold Accessories

Definition

The mold guide sleeve is a solid lubricating product, mainly used in the guiding system of molds, protecting the punch and die, and improving the precision and service life of the mold. Its base material is mostly high-strength brass, inlaid with solid lubricants such as graphite or molybdenum disulfide, which can effectively reduce friction and wear even in oil-free lubrication or high-temperature environments. The product structure features an integral design, integrating flange edge positioning and positioning hole processing functions. It is suitable for various complex conditions such as high pressure, low temperature, and closed structures. By 2025, mold guide sleeves have been widely applied in fields such as automotive molds, metallurgy, plastic injection molding machines, water conservancy projects, construction machinery, paper machines, and ships.

Core value
Double-effect self-lubrication: Embedded high-purity graphite (oil content ≥20%), with a friction coefficient as low as 0.08
Military-grade precision: Inner hole tolerance ±0.003mm, straightness ≤0.005mm/100mm
Extra-long service life: Through 1 million reciprocating tests, the wear is less than 0.01mm
Intelligent heat conduction: With a thermal conductivity coefficient of up to 60W/m·K, it ensures rapid heat dissipation and prevents jamming

Technical parameters
The base material is C93200 tin bronze (CuSn7Pb15)
Graphite purity ≥99.9% (ISO 8002 standard)
Hardness HB 70-85 (can be heat-treated to HRB 90)
Operating temperature: -50℃ to +200℃ (instantaneous 250℃)
Compatible with high-hardness materials such as SKD61/SKH51 guide pins
Certification standards: ISO 9001, RoHS, FDA (optional)

Three major technological breakthroughs
Gradient copper layer structure: A gradual transition from a high-hardness surface layer to a tough substrate
Intelligent lubrication system: Laser micro-hole oil storage technology, with a 40% increase in lubricant retention
