Description du produit

This product is made from imported rubber and formed through high-temperature molding, offering stronger sealing performance and a longer service life. We always strive to produce high-quality products, adhering to rubber processing techniques as our bottom line and ensuring the long-term interests of our customers. Your needs are our shared goal to create!

1. Manufacturing Advantages: Hard Power Supports Quality
2. Vertical Production Line

Our own rubber mixing workshop and mold pressing vulcanization workshop ensure full control over the entire process from raw materials to finished products. Raw materials are purchased in bulk to maintain the consistency of the mixed rubber’s performance and avoid quality fluctuations caused by external processing or unstable performance due to different batches of raw materials. We use an AI visual inspection system to conduct 100% online inspection of the sealing surface flatness and dimensional tolerance (accuracy ±0.1mm), ensuring a 100% qualified rate of products leaving the factory.

2. Cost Control Capability

We have signed long-term price-locking agreements with upstream rubber suppliers to avoid the risk of raw material price fluctuations, with costs 15%-20% lower than those of our competitors. We adopt modular mold design, allowing the same mold to be adapted to multiple brand models for modification, reducing the cost of small-batch customization. We use single-mold sampling to save unnecessary costs for our customers as much as possible.

1. Technological R&D Advantages: Unique Barriers and Superiority
2. Data-driven R&D System

– We have established a database of working conditions for construction machinery engines, accumulating vibration frequency and thermal deformation data for over 100 models, and conducting simulation tests to match the optimal material formula. We have jointly developed a super low-temperature resistant natural rubber formula with universities, which remains elastic at -48°C (industry average -40°C).

2. Small Formula, Multiple Experiments R&D

Using a 3L internal mixer, we analyze customer technical requirements at one time when developing new formulas, and design three schemes (high, medium, and low) based on the actual working conditions of the product for customers to choose from. We conduct multiple frequency experiments on the rubber compound and test its performance in multiple aspects to ensure stable performance when customers use the product.

III. Agile Service Advantages: Quick Response to Customers

1. Non-standard Customization Capability

24-hour rapid response to quotations: We provide 3D scanning/drawings/physical reverse engineering, and deliver small-batch trial products within 7 days (industry average 25 days).

Support for “One Machine, One Solution”: We provide exclusive tracks and sealing solutions for niche construction machinery (such as tunnel boring machines) to solve the problem of no available products in the market.

2. Zero Burden After-sales Commitment

2-hour response: We have set up 8 regional service centers across the country, and urgent orders are delivered to the construction site by SF Express within 48 hours.

– Authoritative Certification: We have obtained the EU CE Machinery Directive Certification, ISO9000 System Certification, and TS16949 Quality System Certification.

From oil seals to tracks, we make the machinery airtight. Hengjun Seals keep your equipment as good as new!
