1. Precision Profile Reconstruction: We reverse-engineer worn, distorted, or missing OEM seals by means of 3D profile analysis and optical measurement, and then we are able to restore original dimensions with high accuracy.
2. Engineered Elastomer Compound: The compound is developed with the use of high-rebound and water resistant polyurethane. The main function of this material is to withstand wear and tear from heavy mining machinery. This includes the resistance against fatigue, tearing, and mechanical wear in the operating temperature range of -35 to +110 degree Celsius that can withstand the short-term maximum of 120 degrees.
3. Tight CNC Machining Tolerances: We precision-turn the seals on CNC lathes to within strict +-0.03mm tolerance. This tight tolerance allows for a proper interference fit that prevents mineral dust ingress while minimizing friction and avoiding damage to the shafts.
4. Predictable Delivery: The flexible nature of our manufacturing processes enables us to deliver standard profiles as well as custom orders within an average of 7 to 15 working days respectively.

The Operational Challenge & Practical Solution
Pain Point: Seal failure caused by continuous vibration
Cone crushers are continuously vibrating and exposed to large volumes of dust. Under this constant exposure to harsh conditions, the dust seal of the crusher can lose its shape or its seal integrity. When the lip of the seals ceases to provide enough pressure at the contact surface, then the fine dust particles will have an entrance route through into the sealed area. This will result not only in increased contamination, but also in accelerated wearing of the parts inside the crusher.
Our Solution: Engineered for stable sealing under vibration
ZHUOYUE Cone Crusher Dust Collar Seals consist of polyurethane material that undergoes repeated deformation and is resilient at the same time due to the polymer formulation used. The polymer is chosen in such a way that it maintains sealing contact through continuous vibration and at the same time restores its original shape after compression, which is one of its main characteristics. Furthermore, the shaping and sizes of the sealing part are decided in conformity with the crusher model, OEM number, drawing, or worn sample so as to guarantee the correct size, and sealing pressure remains constant.
Customer Value: The maintenance periods are easier to foresee when seals have a more stable sealing surface which is the case under continuous vibration, besides dust ingress is prevented and internal components are safeguarded.

Extreme Weather Jobs: Open-pit working places that get hit by cold northwestern winter (-35°C) or hot desert processing climate conditions.
Manufacturing & Quality Verification.
Shenyang Zhuoyue Machinery Equipment Co., Ltd. manufacture replacement wear parts and sealing components specifically for heavy mining machinery. We seal components inspected according to approved CAD drawings, dimensional tolerances, material specifications, and ISO/ASTM standards.
Elastomer CNC Turning: Our solid polyurethane cast tube machining operations are carried out on specialized CNC lathes, effectively eliminating heat degradation and tool mark blemishes common in low-end machining.
Dimension Inspection: With the use of optical projectors and high-precision calipers, every batch of our components is dimensionally inspected against authorized CAD drawings before being released from our workshop.
CAD Engineering Support: In case you do not have original drawings available, our team of engineers shall prepare detailed CAD drawings based on photos and measurements within 24 hours to your approval.
Guarantee & Material Traceability
Fitment Assurance: We guarantee our seals match the dimensions on your approved CAD drawing. If a seal does not fit due to a manufacturing dimension error, we replace it immediately.
Material Test Reports (TDS): Physical property test sheets for our raw PU batches are available upon request for quality review.
Production Progress Checks: Photo and video updates of your order during turning and packaging are available upon request.
4-Step Order Workflow
1. Send Photos / Dimensions ➔ 2. Review & Approve CAD Draft (24 Hours) ➔ 3. Production (7–15 Business Days) ➔ 4. Final Dimension Check & Express Shipping
Frequently Asked Questions
Q: How can I order a replacement seal if the OEM part number is missing?
A: Kindly send us some clear pictures of the worn out seal as well as the main measurements (the inside diameter, the outside dimension, and the cross-section of the seal) or mail us a small sample of it. We will recreate the 2D drawing of the profile, and send you a technical CAD design which you will need to confirm and we will carry out the machining once you sign the order.
Q: Can we order a small sample batch for trial installation?
A: Yes. We accept low-volume sample orders so your maintenance crew can test fitment and performance on site before you commit to large stock quantities.
Q: What is the standard turnaround time for orders?
A: Most standard and customized polyurethane seal orders are completed and dispatched within 7 to 15 business days following CAD drawing approval.
Q: What details do you need to provide a firm price quote?
A: Send your crusher brand and model, reference part numbers (if you have them), key dimensions or sketches, operating temperature range, and the quantity you need.
