Engineering Custom PEEK Components for Demanding Industries
HSealing is a custom PEEK components manufacturer — not a stock distributor. We engineer machined and injection molded parts for valve & pump systems, electrical insulation and semiconductor equipment, where temperature, chemistry and dimensional stability decide whether the part survives in service.
A Components Supplier Built Around Engineering, Not Catalog Trading
HSealing started by solving one frustration shared by engineers across China and overseas: PEEK was easy to buy as rod, sheet or tube — but hard to source as a real, application-ready component, with the right grade selection, the right tolerance discipline, and a supplier that actually understood what the part had to do in service.
We focused our business on two production lines — CNC-machined parts and injection molded parts — and three industries where PEEK delivers measurable value over metals and lower-grade polymers. Today we work with engineering teams from prototype to validated production, treating every order as an engineering project, not a line item.
What We Stand For
Three principles shape how we quote, build and support every PEEK project we take on.
Our Mission
Help engineering teams replace metal and lower-grade polymers with PEEK parts that hold up in real service — chemistry, temperature, load and time included.
Our Vision
To be the engineer's first choice for custom PEEK components — known for honest material guidance and consistent batch quality, not the lowest catalog price.
Our Approach
Drawing-driven quotes with material recommendation and DFM feedback. We quote what we can build, build what we quoted, and support reorders with the same engineer who quoted it.
Capability at a Glance
What Makes Us Different
We position ourselves as a custom components supplier — that changes everything about how we engage with your project.
Drawing-Driven Quotes
Send STEP, IGES or annotated PDF — we respond with material recommendation, tolerance review and a real production quote, not a generic price list.
Prototype to Production Path
Validate the design with CNC samples, then transition to injection tooling once volume justifies it — managed by one team under one quality standard.
Honest Material Guidance
Unfilled, glass-, carbon- or wear-modified PEEK — we recommend the grade that fits your service environment, not the one that maximizes our margin.
Process Discipline for Molding
PEEK injection requires controlled melt temperature, gating and tooling design. We apply real process control instead of treating PEEK as commodity plastic.
From First Drawing to Repeat Order
Send Drawings
STEP, IGES, DWG or annotated PDF — with quantities and target application.
DFM & Material Review
We confirm tolerances, recommend the best PEEK grade and flag risk areas.
Quote & Lead Time
Transparent pricing for prototype, short run and tooled production options.
Sample & Approval
First articles with inspection report. You approve before any volume runs.
Production & Reorder
Repeatable process, consistent batches, fast reorder turnaround.
Built to Pass Inspection — Yours and Ours
Every part leaves our facility against the drawing it was quoted to. We take quality seriously because our customers' equipment runs on what we ship.
- Dimensional inspection report on first articles
- Material certificates traceable to the resin batch
- Repeatable process control for molded production
- NDA available on request — drawings stay confidential
- Single point of contact from quote through reorder
