Development History
20 years of industry production experience, professional R&D and
design team
2008
Foundation & Initial Start of Powder Metallurgy Shock Absorber Parts
Company was officially founded, focusing on the R&D and small-batch mass production of
powder metallurgy components for automotive and motorcycle shock absorbers. We centered on
core shock absorber piston products, built basic production workshops and a preliminary
R&D lab, and set powder metallurgy shock absorber accessories as our core business
track, embarking on the path of independent auto component manufacturing.
2012
Self-developed Automatic Equipment, Assembly Line Production for Rubber-Coated Pistons
Drawing on years of R&D experience in piston manufacturing, we independently designed and
manufactured dedicated automatic rubber coating machines and precision grooving equipment
for shock absorber pistons. We built an integrated assembly line for rubber-coated pistons,
greatly improving production precision and delivery efficiency of pistons and matching
rubber sheets, achieving a sharp leap in product yield and supplying OEM customers in bulk.
2015
Expanded Stamping Product Line, Enriched Precision Component Portfolio
We expanded our production division and launched mass production lines for stamped parts
including spring seats, shock absorber brackets and high-precision valve plates. Meanwhile,
we upgraded the powder metallurgy sintering workshop and optimized the dense forming process
for sintered shock absorber parts. Dual production lines for powder metallurgy and stamping
components were fully operational, greatly diversifying our product range.
2018
Automated Rubber & Plastic Production Line Launched, Upgraded Rubber Component Capacity
We completed the construction of fully automatic production lines for shock absorber rubber
and plastic accessories, introducing integrated automatic mixing, molding and trimming
equipment. The automation level and daily output of rubber & plastic products doubled,
solving mass supply challenges for shock absorber sealing and buffer parts, and completing
our rubber & plastic supporting segment.
2020
New Piston Rod Production Line Launched, Extended Vertical Supporting Chain
We introduced professional precision machining lines for shock absorber piston rods to
realize in-house mass production. A dedicated workshop for shock absorber springs was also
put into operation with mass spring delivery. Our product portfolio expanded from pistons,
stamped parts and rubber components to piston rods and shock absorber springs, significantly
strengthening our vertical industrial supporting capacity.
2022
Full Product Coverage, One-Stop Supply Chain for Shock Absorber Parts
Our product line kept expanding, with large-scale production covering all shock absorber
accessories including powder metallurgy rubber-coated pistons, stamped structural parts,
rubber sheets, piston rods, shock absorber springs and valve plates. We basically
established a closed-loop full-category supply chain for automobile and motorcycle shock
absorber parts, capable of delivering complete supporting solutions to global clients.
2024
Annual Output of Core Pistons Hits 50 Million Pieces, Boosted Industrial Competitiveness
The full capacity of powder metallurgy rubber-coated pistons was unlocked, reaching an annual
output of 50 million core pistons. We continuously upgraded forming, sintering and rubber
coating technologies, making our product precision and wear resistance reach international
top-tier standards. Our supporting share for domestic vehicle manufacturers grew steadily,
and our comprehensive competitiveness in the industry improved remarkably.
2026
Full-Range Technical Support, One-Stop Sourcing & Industrial Chain Service
With over a decade of technological polishing, process innovation and project experience
accumulation, we established a mature professional technical service team. Our service
system has been fully upgraded: we provide global customers with one-stop sourcing services
for auto and motorcycle shock absorber parts, as well as full-industry-chain customized
technical support covering powder metallurgy, shock absorber overall design, tooling
installation and product development. We help clients break through R&D and production
technical barriers, evolving into an integrated shock absorber component supplier with
outstanding manufacturing strength and comprehensive technical service capabilities.
