Jaw Crusher Fixed Jaw Plate | Wear-Resistant Casting for Mining & Aggregate Crushing

1. Product Description

The fixed jaw plate is one of the most critical wear components in a jaw crusher. It forms the stationary crushing surface that works together with the moving jaw plate to compress, bend, and fracture material during the crushing cycle. Because it bears continuous impact, compression, and abrasive wear, the choice of jaw plate directly affects crushing efficiency, product output, and the frequency of maintenance shutdowns.

Our fixed jaw plates are produced through integrated precision casting, followed by heat treatment, machining, and full inspection. The result is a wear part with consistent material density, accurate tooth geometry, and reliable performance under heavy-duty working conditions.

Whether you operate a stationary crushing plant or a mobile jaw crusher, we can supply fixed jaw plates matched to your equipment model, feed size, and material characteristics.

2. Key Features

Consistent Casting Quality
Integrated precision casting produces a dense, uniform internal structure without porosity or shrinkage defects, providing a reliable foundation for long-term wear performance.

Accurate Tooth Geometry
Precision machining and shaping ensure regular tooth profiles and proper bite fit, maintaining stable crushing efficiency throughout the service life of the plate.

Strong Impact Resistance
Designed to withstand high-impact crushing conditions, the plate resists tooth breakage, cracking, and deformation far better than standard replacement parts.

Lower Wear Rate
Optimized material selection and heat treatment deliver a lower wear rate, extending replacement intervals and reducing total operating cost per ton of crushed material.

Stable Performance Over Time
Heat treatment refines the metallographic structure and relieves internal stress, keeping the plate stable in both hardness and toughness throughout its working life.

Custom Fit
Available in multiple materials, thicknesses, and tooth profiles to match specific crusher models and application requirements.

3. Material Options

Material selection is matched to the customer's equipment model, feed material, and working conditions to achieve the best balance of wear life and cost.

5. Manufacturing Process

Step 1 — Precision Casting
Molten metal is poured into precision molds to form the jaw plate blank with a dense, uniform structure.

Step 2 — Heat Treatment
Integrated heat treatment refines the internal metallographic structure, eliminates casting stress, and optimizes hardness, toughness, and fatigue resistance.

Step 3 — Machining & Shaping
The plate is precision machined to achieve accurate tooth profile, flatness, and mounting dimensions, ensuring correct fit and assembly.

Step 4 — Full Inspection
Each finished plate undergoes comprehensive inspection before packaging and delivery.

6. Quality Control

Every jaw plate is inspected through a full-item quality control system covering:

• Hardness Testing — Confirms wear resistance strength

• 3D Scanning — Verifies dimensional accuracy for zero assembly error

• Magnetic Particle Testing (MT) — Detects surface cracks, sand holes, and defects

• Ultrasonic Testing (UT) — Detects internal cracks and cavities

• Material Composition Analysis — Confirms raw material ratio and material purity

• Precision Dimensional Inspection — Controls machining tolerances

• Metallographic Analysis — Verifies internal microstructure

All inspection results are documented, and quality inspection reports can be provided with delivery. Production is fully traceable from raw material to finished product.

7. Customization Service

We support both standard model supply and non-standard custom manufacturing.
