Product Scope: Industrial Pins and Plastic Bushings
The exhibition product range includes two functional systems:
These two systems are used together in mechanical assemblies where one component defines position (pins) and the other controls motion and friction (bushings).
Dowel Pins: Rigid Positioning in Mechanical Structures
Dowel pins are solid cylindrical components installed into reamed holes to define fixed positioning between mechanical parts. In assemblies, they control X-Y alignment while bolts provide axial clamping force.
They are commonly used in mold plates, gearbox housings, CNC fixtures, and engine assemblies where repeated assembly cycles require consistent geometric positioning.
Slotted Pins: Elastic Fit for Tolerance Compensation
Slotted pins are rolled from spring steel with a longitudinal slot. The slot allows radial compression during insertion and generates continuous contact pressure inside the hole.
They are used in mechanical structures where machining tolerance variation exists, such as machine housings, structural covers, and general industrial assemblies. Their function is to maintain engagement while compensating for minor dimensional deviations.
Spring Pins: Vibration Control in Dynamic Systems
Spring pins are hollow cylindrical fasteners that deform elastically under load. During installation, the pin compresses and expands against the hole wall, generating frictional force.
They are widely used in automotive systems, agricultural machinery, and industrial equipment operating under vibration and cyclic load conditions. Their function is to maintain joint stability when mechanical vibration causes micro-movement between components.
Coiled Spring Pins: Shock Load Distribution Structure
Coiled spring pins are formed by multiple layers of steel strip wound into a spiral structure. This multi-layer design distributes stress across several contact surfaces instead of a single slot.
They are applied in heavy-duty mechanical systems such as construction machinery, gear assemblies, and rotating equipment where impact load, misalignment, and fatigue stress occur frequently.
Compression Limiters
A compression limiter is a metal tube installed inside plastic parts to control bolt tightening force. When a screw or bolt is tightened, the load is transferred through the limiter instead of directly compressing the plastic, which prevents cracking, creep deformation, and long-term loosening.
It is typically made from carbon steel or stainless steel and used in injection-molded housings, electrical enclosures, automotive plastic components, and industrial covers. During assembly, the limiter defines a fixed stop so the torque is absorbed by the metal sleeve while the plastic part only provides structural support and positioning.
Combined Engineering Function of Pins and Bushings
In mechanical design systems, pins and bushings are often used together to control different mechanical behaviors:
Pins define fixed positioning and load transfer paths
Bushings control sliding motion and reduce friction wear
Both components stabilize mechanical assemblies under vibration and thermal variation
Typical operating conditions include:
Vibration frequency: 20–500 Hz depending on equipment type
Temperature range: -40°C to 120°C in industrial environments
Repeated assembly cycles in maintenance systems
This combination is widely used in automotive subsystems, machinery joints, automation equipment, and tooling fixtures.
OEM Manufacturing Capability
Anhui Pins Metal Products Co., Ltd supports OEM production for both metal and polymer components, including:
Carbon steel and spring steel pin manufacturing
Heat treatment for hardness and wear resistance control
Surface finishing such as zinc plating and oxidation
Injection molding for plastic bushings based on wear and friction requirements
