Long term cooperative customers can enjoy: ① Exclusive technical consultant docking, providing full process support for pre selection and post maintenance; ② A stable price system and inventory guarantee to avoid fluctuations in raw materials affecting procurement costs; ③ Priority cooperation rights for new product research and development, synchronous development of adaptive sealing solutions for customers' new model needs, to help products quickly land.

The minimum order quantity for standard model products is 500 pieces, and the minimum order quantity for customized products can be negotiated; The delivery cycle for regular orders is 3-7 working days. For large orders (such as a single order of more than 100000 pieces), it needs to be determined according to the production schedule, generally not exceeding 15 working days. For urgent orders, priority production services can be provided.

① Customers are required to provide photos of the problematic product, order number, and detailed fault description (such as leakage location and working conditions) within 30 days after receiving the goods; ② Our technical personnel will respond within 24 hours to determine the cause of the malfunction; ③ If it is confirmed to be a product quality issue, free replacement, return, or technical rectification can be chosen. For installation issues, on-site guidance or remote technical support will be provided.

The product needs to go through multiple testing stages: ① Raw material testing (such as metal material composition analysis, corrosion resistance testing); ② Production process testing (such as dimensional accuracy calibration, sealing surface flatness testing); ③ Finished product testing (such as static sealing at 1.5 times the working pressure for 30 minutes, with a pressure drop of ≤ 5%), and some high-end products can also provide ASME related standard certification support.

The principle of "material compatibility" should be followed: ordinary rubber seals can use silicone grease; Ordinary butter is prohibited for PTFE material seals (which can cause material expansion), and it is recommended to use perfluoropolyether (PFPE) lubricant; Oil seal products should be matched with lithium based grease compatible with engine oil to avoid affecting the sealing life due to improper lubrication.

Common issues include installation misalignment, damage to sealing surfaces, and uneven bolt tightening. Avoidance method: ① Clean the sealing surface of the cylinder body and cylinder head before installation, remove burrs and residual gaskets; ② Tighten the bolts in the order specified in the engine manual to avoid local stress concentration; ③ Perform a 15-30 ° chamfer treatment on the contact areas such as the shaft end and hole opening to prevent scratching of the sealing components during installation.

Okay. For special requirements of non-standard or modified engines, we can provide customized services. Customers need to provide detailed installation dimensions, operating parameters (such as maximum working temperature, design pressure), and sealing performance requirements. Through dedicated CNC machining equipment, precise customization can be achieved to ensure adaptability and reliability.

Three core pieces of information need to be provided: first, the specific model of the engine (such as displacement and manufacturer), second, the actual working conditions (such as long-term operating temperature and whether it is used for retrofitting and strengthening), and third, the sealing requirements (such as whether it can withstand high-pressure conditions). We will match cylinder gaskets made of suitable materials such as 316Ti stainless steel and Inconel based on temperature, pressure, and medium characteristics to avoid seal failure caused by improper selection.

The company has Liangtian Xuantian Seal Manufacturing Factory in Baiyun District, Guangzhou as its exclusive production base, equipped with more than ten advanced domestic automated seal CNC machining platforms, complete mechanical arm production lines, and multiple laser processing equipment, forming a standardized production system that can stably guarantee the delivery of large orders and product accuracy control.
