Our Process

From Drawing to Production — A Process Engineers Trust

Every PEEK part we ship goes through the same disciplined path: drawing review, material selection, transparent quoting, sample approval, then production. No shortcuts, no surprises, no "we'll figure it out later."

Why Process Matters

PEEK Is Not Forgiving — Our Process Is Built Around That

PEEK is one of the most demanding engineering polymers to machine and mold. Wrong material grade, wrong gating, wrong tolerance assumption — and the part fails in the field, weeks after it leaves the factory. We've built our process specifically to catch these issues before quoting, not after shipping.

What you get is a single accountable workflow: the same engineer who reviews your drawing also approves your first article and supports your reorder. No handoffs, no information lost between teams.

The 5-Step Workflow

How Your Project Moves Through HSealing

From the first email to repeat orders — here's exactly what happens, when it happens, and what we deliver at each step.

1

Send Drawings & Requirements

Day 0

You send us drawings and tell us what the part has to do. The more we know about the service environment, the better we can recommend material and tolerance.

What you provide

  • STEP / IGES / DWG / annotated PDF
  • Quantity (prototype, short run, volume)
  • Service temperature, chemicals, load
  • Target lead time

What we do

  • NDA available before drawings shared
  • Acknowledge receipt within 4 business hours
  • Assign a single engineer to the project
2

DFM Review & Material Recommendation

Day 1–2

Before we quote, we review the design. We flag tolerance risks, suggest material grade based on your environment, and tell you honestly if a feature should be redesigned.

What we check

  • Tolerance feasibility for chosen process
  • Wall thickness, gating, mold release (for molded parts)
  • Grade fit: unfilled, GF, CF, wear-modified
  • Cost-saving design alternatives

What you receive

  • Written DFM feedback
  • Recommended PEEK grade with reasoning
  • Optional: short call with the assigned engineer
3

Transparent Quote & Lead Time

Day 2–3

You get a real engineering quote — broken down by stage, with lead time and material included. No "TBD" lines, no surprise add-ons later in the project.

Quote includes

  • Unit price by quantity tier
  • Tooling cost (for molded parts)
  • Sample lead time and production lead time
  • Material grade and certificate availability

Quote terms

  • Quote valid 30 days
  • Payment terms negotiable for established customers
  • EXW / FOB / DDP shipping options
4

Sample Production & Approval

Week 1–4

We produce first articles — CNC samples or T1 mold trial — and ship them with a full inspection report. You approve before any production volume runs.

Sample deliverables

  • First article inspection (FAI) report
  • Material certificate traceable to resin batch
  • Photos of critical features
  • Notes on any process observations

Approval flow

  • You inspect & sign off on samples
  • Revisions discussed before production starts
  • No volume run without written approval
5

Production, Shipment & Reorder

Ongoing

Once samples are approved, we lock the process. Future batches reproduce the same quality you signed off on — and reorders go through your same engineer, no re-explaining.

Production discipline

  • Locked process parameters per part
  • Batch inspection records retained
  • Material traceability per shipment
  • Worldwide air or sea shipping

Reorder support

  • Same engineer, same process, same quality
  • Reorder lead time often 30–50% shorter
  • Proactive resin/grade availability alerts
Two Production Tracks

Same Process, Different Path

The 5 steps stay the same. What changes is whether your part runs through CNC machining or injection molding — chosen based on your design, quantity and tooling appetite.

Track A

CNC Machining Path

For prototypes, short runs, complex high-precision parts, or any project where investing in tooling doesn't make sense yet.

DrawingDFMQuote CAM ProgrammingMachiningInspectionShip
Typical Lead Time 5–10 working days
Best For 1 to ~5,000 pcs
Track B

Injection Molding Path

For locked designs with sustained volume — the process discipline pays off in batch consistency and long-term unit cost.

DrawingDFMMold Quote ToolingT1 TrialApprovalProduction
Typical Lead Time 4–8 weeks (incl. tooling)
Best For 5,000+ pcs / year
Quality Built In, Not Bolted On

What "Quality" Actually Means at HSealing

Three commitments that run through every step of the process — not just at the final inspection bench.

Inspection Reports

First-article inspection on every new part. Batch inspection records retained for production runs and available on request.

Material Traceability

Every shipment ties back to the resin batch and grade certificate. If a material question comes up later, we can answer it.

Locked Process

Once samples are approved, parameters are locked per part. Reorders reproduce the exact part you signed off on — not a "close enough" version.

Process FAQ

Common Questions About Working With Us

Do I have to commit before seeing a quote?

No. Quoting and DFM review are free. We only ask for commitment when you approve the quote and place an order.

What if your DFM review suggests changes?

We send written feedback with reasoning. The decision is always yours — we'll quote your design as-is, but we'd rather flag a risk than ignore it.

How do you handle revisions during sampling?

Minor revisions on CNC samples are usually included in the original quote. Mold revisions are quoted separately because tooling work has real cost.

Can I visit the facility or video-audit?

Yes. We host customer visits by appointment and run video audits for international customers. Talk to your assigned engineer to schedule.

Do you support production scaling later?

Yes. Many customers start with CNC samples, validate the design, then move to molded production once volume justifies tooling. We support both paths.

What happens if a shipment has a defect?

We investigate the root cause using batch records, replace defective parts, and document the corrective action. Quality issues don't get ignored.
