Comprehensive QC Program Design
We design complete quality control programs covering incoming material inspection, in-process quality checkpoints, final product inspection and sign-off, defect identification and classification systems, and quality documentation and record-keeping — all tailored specifically to window and door manufacturing.
Statistical Process Control & Continuous Improvement
Beyond establishing baseline quality controls, we implement SPC methodologies and help build a culture of continuous improvement. This includes regular quality audits, trend analysis, root cause investigation, corrective and preventive action (CAPA) frameworks, and targeted training for production staff.
Standards Compliance Integration
Our QC programs are designed to meet the requirements of AAMA/WDMA/CSA 101 (NAFS), ENERGY STAR, and relevant building codes. This alignment ensures your factory quality program directly supports your certification and compliance objectives, reducing redundancy and audit risk.
