We mold the rollers, buffers, end caps and retainers that let heavy-duty drawer slides run smoothly for 100,000 cycles — supplying Hettich, FGV and OEM partners worldwide since 2003.
Co-engineered with slide makers, molded in-house, and shipped ready for your assembly line.
POM-C and POM+PTFE rollers for smooth travel under heavy loads — concentricity held to 0.03 mm.
to 80 kg / pairTravel-limit and closure parts engineered for repeated impact without cracking or creep.
impact-modified POMTPE and 2K-overmolded buffers that define the soft-close feel of a premium slide.
2K overmoldingThin-wall precision cages that keep bearing balls aligned across the full stroke, season after season.
thin-wall 0.6 mmQuick-release levers and mounting clips with living hinges validated over 10,000 actuations.
PA66-GF30Send a step file or a problem. We answer with DFM feedback in 48 hours and a T1 sample plan.
DFM in 48 hSlide components live or die by friction, creep and fatigue. We specify and mold engineering resins from Celanese, DuPont and BASF — with full batch traceability.
CNC, EDM and wire-cut tool shop. T1 samples in 25 days; tools built for 1M+ shots with full maintenance records.
Cavity-pressure monitored processes, decoupled molding, and documented process windows for every part number.
Dedicated two-shot cells for hard-soft combinations; steel and brass insert overmolding for load-bearing functions.
Sub-assembly, kitting and customer-specific packaging — parts arrive line-ready, not bag-ready.
Full IQC → IPQC → OQC flow with PPAP-style documentation packs for every new launch.
Coordinate measuring, optical projection and force-displacement testing on climate-controlled benches.
In-house cycle rigs run loaded slides day and night — because a buffer that survives 100,000 closes sells the next million.
Every new roller, buffer and retainer design earns its release the hard way: under full rated load, to failure or to spec — whichever comes last.
Hengsu Precision was founded in 2003 in Guangdong — the heart of the world's furniture-hardware supply chain. Today the second generation runs the plant, with the same principle the first generation built it on: the parts nobody sees deserve the most care.
We are deliberately specialized. We don't mold everything for everyone — we mold the polymer components of heavy-duty motion, and we do it well enough that the world's most demanding slide makers keep coming back.
