Quality Assurance & Quality Control
At SZ-MOLDTECH, quality is built into every stage of PET preform mould manufacturing, not added at the final inspection.
Complete Process Coverage
Quality extends from material selection and precision machining through mould testing, installation and production verification at the customer's site.
Certified & Standardized
ISO-supported quality management and CE-aligned products give our process control and product conformity a recognised framework.
Engineered For Your Line
Beyond delivery, our engineers think in terms of your production line, machine fit, cycle time and long-term output.
Why Our PET Preform Mould QC Approach Stands Out
-
Inspection at Every Critical StageCritical mould components are inspected throughout machining, finishing, measurement, and assembly. Drawing-based inspection helps control key dimensions, interfaces, and alignment before the mould reaches the trial stage.
-
Every Mould Is Trial-TestedBefore delivery, the completed PET preform mould is installed for trial moulding. Preform weight, neck finish, appearance, dimensions, and production consistency are reviewed to verify actual mould performance.
-
Support Beyond Factory AcceptanceOur engineers can assist with on-site mould installation, commissioning, troubleshooting, and initial production. This creates a continuous process from manufacturing and trial moulding to stable production.
Process Inspection Coverage
How We Inspect PET Preform Moulds at Every Stage
Every critical manufacturing stage is followed by a dedicated inspection. Components are checked against drawings and specifications before moving to the next process, helping prevent errors from carrying through to final PET preform mould assembly.
Material & Component Inspection
Incoming materials and critical mould components are checked against approved specifications before machining begins. Material condition, dimensions, and key requirements are verified to establish a reliable foundation for PET preform mould manufacturing.
CNC Machining Inspection
Machined dimensions and critical tolerances are inspected after CNC processing. Early dimensional checks help identify deviations before they affect cavity alignment, component fitting, or final mould performance.
EDM, Grinding & Polishing
EDM profiles, ground surfaces, and polished areas are inspected for accuracy and finish quality. Critical cavity surfaces, neck finish areas, and interfaces are checked before components proceed to assembly.
Precision Measurement & Cavity Inspection
Critical dimensions are measured against engineering drawings and defined tolerances. Cavity, core, neck finish, and key interface dimensions are verified to support consistent PET preform production across multiple cavities.
Precision Mould Assembly
Each mould component is checked for fit, alignment, movement, and assembly accuracy. Special attention is given to cavity and core alignment, mould interfaces, and moving components before the mould enters trial production.
Trial Moulding & Performance Verification
The completed PET preform mould is tested through trial moulding before shipment. Preform weight, neck finish, appearance, dimensions, and production consistency are reviewed to verify mould performance under practical operating conditions.
Quality Assurance FAQ
Common questions about coverage, trial testing, lead time, service life and material standards.
What is covered by your quality assurance?
Coverage runs from material selection and precision machining through mould testing, on-site installation and the first stable production runs.
What checks are included in trial mould testing?
Preform weight consistency, neck finish dimensions, product appearance, moulding stability, component alignment and production repeatability.
What is the typical lead time for delivery and on-site support?
Lead time depends on mould configuration and project scope. After trial moulding, on-site engineer support can be arranged to assist installation, commissioning and initial production.
What mould service life can we expect?
Service life depends on mould design, materials, operating conditions, maintenance and production environment. Actual figures should be confirmed per project.
Which mould materials and component standards do you work with?
We work with the steel grades and component standards typically specified for PET preform moulds, and can adjust material selection to your cavity, neck and cooling requirements.
