Hongtai Doors & Windows relies on a modern production base of over 20,000 square meters. Following Australian Standards (AS2047, AS2208) and the ISO9001 quality management system, we’ve built an end-to-end service process—from raw materials to finished products, and on to professional installation. This ensures our products meet the needs of high-end markets at home and abroad. The key steps are as follows:

•Supplier Selection: We prioritize imported profiles, German hardware parts, and AS2208-certified glass. This helps us ensure material compliance right from the supplier side.

•Strict Testing: Our Quality Control (QC) team samples and tests each batch of raw materials. We focus on checking key indicators like profile thickness, glass pressure resistance, and hardware durability. Any substandard materials are sent back immediately—no exceptions for production use.

•Classified Storage: Qualified raw materials are stored by type and specification. Glass is kept in a temperature-and-humidity-controlled warehouse to prevent moisture damage or scratches. We also maintain an inventory record to track all materials easily.

•Drawing Breakdown: Based on custom customer needs or project blueprints, our engineering team turns design plans into production parameters and inputs them into smart CNC systems.

•CNC Cutting: We use advanced CNC cutting machines to cut profiles with high precision—error is kept under 0.5mm to ensure accuracy for later assembly.

•Detailed Processing: Using CNC milling machines, drills, and other equipment, we drill holes, make grooves, and smooth edges on profiles. For cyclone-resistant doors/windows (with special structures), we add extra reinforcement bars to boost product stability.

•Frame Assembly: Workers piece processed profiles into door/window frames following production standards. Special connectors are used to keep frames square and free from deformation.

•Hardware Installation: We fit imported German hardware (like hinges, locks, and handles) precisely. We test the smoothness of opening/closing repeatedly to ensure good usability and durability.

•Sealing Optimization: High-elasticity seal strips are added between frames, glass, and profile joints. Automated gluing machines apply sealant evenly—this improves water tightness and air tightness, making products suitable for Australia’s rainy, windy climate.

•Glass Cutting and Cleaning: Glass is cut to match door/window sizes. Professional cleaning equipment removes dirt and dust from the glass surface to avoid affecting light transmission and sealing.

•Glass Fitting: Clean glass is inserted into frames and fixed with double-sided gluing. This ensures the glass fits tightly with no looseness or gaps.

•Pre-Assembly Testing: We test fully assembled doors/windows by simulating real use—checking how well they open/close and if locks are secure. Any issues found are fixed right away to prevent problems in later steps.

•Comprehensive Testing: The QC team conducts full tests on doors/windows (including wind pressure resistance, water tightness, air tightness, and sound insulation) according to Australian and international standards. A test report is issued, and substandard products are not allowed to leave the factory.

•Labeling: Qualified products are labeled with model numbers, order IDs, production dates, and QC passed marks. This makes it easy to track logistics and help customers trace their products later.

•Custom Packaging: We use multi-layer packaging (like shock-absorbing foam, cardboard, and wooden frames) based on product size and shipping needs. For products exported to Australia, extra moisture-proof packaging is added to prevent damage during transport.

•Order Matching: The logistics team creates shipping plans based on delivery addresses and deadlines. For domestic projects, we prioritize direct truck delivery. For products exported to Australia and other overseas markets, we work with professional foreign trade logistics providers.

•Pre-Shipment Check: Before shipping, we recheck product models, quantities, and order details. Only after confirming everything is correct do we process the shipment.

•Delivery Follow-Up: We track logistics in real time and update customers on shipping progress. For domestic projects, we coordinate with the installation team to align delivery times. For overseas projects, we provide product certification documents needed for customs clearance to ensure smooth delivery.
