Illustration of the plastics supplier’s head of quality praising Werk24 feasibility gates

“Werk24 flags out-of-policy tolerances and critical finishes at intake. Our team focuses on real risks instead of hunting for details in PDFs.”

— Head of Quality, Global Plastics Supplier

The challenge

Injection-molded parts arrive with diverse drawings: mixed units, varying tolerance policies, and finish notes buried in PDFs. Manual reading slowed intake and created quality exposure — tight tolerances, special finishes, or threads were occasionally missed, becoming costly NCRs later.

Variability:every customer uses different PMI conventions
Hidden risk:subtle tolerances & surface finishes discovered late
Throughput limit:intake speed capped by manual QA checks

Quality leaders needed automated feasibility checks at intake to protect margin and throughput.

Why now

Higher RFQ volume demanded standardized, auditable intake
Customers expected faster, accurate feasibility decisions
No desire to maintain templates or brittle custom parsers

The Werk24 solution

Feasibility gates powered by structured PMI

Werk24 reads 2D mechanical drawings — components & assemblies, including acceptable scans — extracting title-block metadata and feature data (dimensions with tolerances, GD&T, threads, surface roughness). It also delivers insights like external dimensions and process hints (DIN 8580).

Deterministic JSON or custom output matching ERP/QMS fields
Policy checks for unit normalization, tolerance bands, finish rules
No training data required to start; optional custom quality gate to push certain features to ~99%

Integration & governance

REST + webhooks and the Python SDK push results into ERP and QMS. Confidence thresholds auto-accept high-certainty fields and route edge cases for review. Compliance is covered with EU/US data residency and zero-retention on higher tiers.

REST API & Python SDK; webhooks for lights-out routing
Per-field confidence scores + human-in-the-loop on exceptions
EU or US processing; zero-retention option on provisioned/enterprise tiers

Implementation in days

Day 1–2: trial key, sample drawings, policy mapping (tolerance/finish rules)
Week 1: intake gates live; confidence thresholds tuned
Week 2+: expansion to inspection planning & QMS reporting

No labeled training data required — custom gates optional.

From developer: inside for developers: inside

Clean APIs, predictable JSON, confidences and webhooks. From PDF to production in hours instead of weeks.

            pip install werk24    # Install Werk24
werk24 init           # Obtain a trial license
werk24 health-check   # Verify connection

            from werk24 import read_drawing_sync, get_test_drawing, AskMetaData
print(read_drawing_sync(get_test_drawing(), [AskMetaData()]))

Tip: Use webhooks/callbacks for dark processing and confidence thresholds.
