2026-7-22 The customer's goods sent

July marks a new beginning: SINO CHOICE has shipped its first batch of core components for heavy-duty trucks in 2026, leveraging comprehensive capabilities to empower the global commercial vehicle market. On July 22,2026, as summer morning light began to illuminate the freight corridors of the logistics park in Jinan, orderly operational sounds could already be heard outside SINO CHOICE's storage facility. After nearly a week of meticulous preparation, item-by-item inspection, and standardized packaging, containers loaded with core components from Sinotruk and Shaanxi Auto Industry Group gradually departed the park, ready to embark on their journey to Central Asia. This represents another key order delivered by SINO CHOICE in the second half of 2026, featuring over 30 categories of core components covering the entire system of heavy-duty trucks—including power systems, transmissions, steering mechanisms, braking systems, and body structures. Carrying the quality reputation built through 17 years of expertise in commercial vehicle parts, these components will reach overseas customers, providing stable and reliable performance support for local logistics and construction vehicles.
This shipment delivers comprehensive core components covering all operational scenarios for heavy-duty trucks. Each part has undergone rigorous quality inspections by our team, meeting original manufacturer specifications from material precision to fit parameters, and comprehensively addressing essential wear parts and critical assemblies required for daily maintenance and major overhauls. For powertrain components, the main bearing shells and connecting rod bearings employ high-tin aluminum alloy coatings with micron-scale oil reservoir grooves that maintain stable lubrication film thickness under high-load conditions – effectively reducing wear between journal and bearing shells even during demanding mountainous drives or continuous construction operations, significantly extending engine overhaul intervals. Valve guides utilize powder metallurgy carburization technology with internal surface roughness controlled below Ra0.8, ensuring guidance accuracy through thousands of high-frequency valve cycles while preventing valve wear or leakage. The centrifugal oil filters leverage rotational centrifugal force to remove metal particles and contaminants, achieving filtration performance far superior to conventional paper filters. Combined with filter cartridge assemblies with mounting interfaces, these systems provide dual filtration protection, maintaining optimal oil cleanliness and establishing robust safeguards for critical engine components. The core components delivered in this batch—including fuel injector assemblies, air compressor assemblies, starter assemblies, and water pumps—all underwent bench simulation tests. The fuel injector's atomization cone angle and injection pressure errors were controlled within ±1%, while the air compressor's charging efficiency fully complied with OEM calibration standards. The starter ensures smooth operation even at low temperatures of-35°C, meeting stringent requirements for cold regions such as Russia and Kazakhstan. Transmission and drive system components constitute another key focus of this order: the steering shaft assembly, manufactured through integral forging, passed 100,000 cyclic torsion fatigue tests without deformation, delivering precise steering torque while eliminating excessive play risks. The gear teeth are fabricated from 20CrMnTi alloy steel via carburizing and quenching, achieving surface hardness of HRC 58–62 with grinding accuracy meeting Grade 6 specifications per GB/T 10095; they maintain smooth engagement even under prolonged operation at full load (50 tons), preventing tooth scoring or abnormal noises. The planetary carrier assembly, cast in monolithic steel with dynamic balancing, evenly distributes torque during differential operation, significantly reducing gear wear under heavy off-road conditions. Key bushing components—including those for steel plate lifting lugs, camshafts, and rear stabilizer bars— utilize high-wear-resistant composite materials combining modified rubber and copper-based powder metallurgy, offering over threefold enhanced durability compared to traditional rubber bushings. This innovation substantially reduces operational noise and component looseness, lowering subsequent maintenance costs for customers. The components of braking and auxiliary systems directly impact vehicle operational safety. The air dryer assemblies delivered this time feature high-flow desiccant filters that efficiently remove moisture and impurities from compressed air, preventing ice formation in brake lines and valve corrosion. The accompanying air drying tanks support long-term use up to 100,000 kilometers while offering significantly improved replacement convenience. The clutch power pump assemblies utilize imported sealing components, eliminating pressure leaks or oil leakage even under frequent clutch application, thereby reducing driver effort and enhancing comfort during long-distance drives. The main power switch employs high-current pure copper contacts capable of instant switching of high-voltage currents, preventing battery depletion and electrical short circuits during prolonged parking – ensuring comprehensive electrical safety. Additionally, rear wheel oil seals feature fluororubber double-lip structures that maintain sealing performance in high-temperature and dusty environments, effectively preventing lubricant leakage from the rear axle. Expansion tank assemblies are made of temperature-resistant modified nylon with excellent impact resistance, preventing coolant overheating and overflow. Multi-wedge belts and generator belts use imported chloroprene rubber formulations reinforced with high-strength aramid fibers, offering superior tensile strength and minimal elongation, ensuring durability against cracking or slippage even during extended operation in hot conditions.
