Our Factory & Production Base

Anchor-tech operates a 50,000 m² production base in Guangzhou, China, dedicated to nano microporous insulation manufacturing. Board forming, CNC precision cutting, facing lamination (PE film, aluminum foil, glass fiber fabric), and final inspection are integrated under one roof, so tolerances, facing quality, and lead times are controlled in-house rather than outsourced step by step.

  • In-house lamination lines for PE, aluminum foil, and glass fiber fabric facings
  • CNC cutting for custom shapes, arc segments, and tight dimensional tolerances
  • Batch traceability from raw fumed silica to the finished board

Quality Control & Batch Testing

Every production batch is sampled and tested before packing. Thermal conductivity is measured at multiple temperature points following YB/T4130-2005, and boards are checked for density, thickness tolerance, and surface integrity. Test data is recorded per batch, so customers can trace the performance of the exact material shipped to them. Third-party testing can be arranged on request for project orders.

Why engineering buyers trust About Us

Anchor-tech track record

The Guangzhou production facility spans approximately 50,000 square metres of built floor area on a 75,000 square-metre site. Pressing capacity is distributed across three lines running at 1.5 m³ per hour per line at typical density, giving a nameplate annual capacity of 6,000 m³ of finished microporous board equivalent. Storage capacity on-site covers approximately 600 m³ of finished inventory at any time, allowing us to maintain buffer stock on the highest-volume stock items (1000 × 1200 mm panels at thicknesses 20, 25, and 30 mm) and respond to spot orders with 5–10 working days of ex-works dispatch. The factory is located approximately 35 km from Nansha Port and 65 km from Guangzhou Baiyun International Airport, which keeps inbound raw-material logistics and outbound container-loading logistics within efficient trucking distances.

Anchor-tech track record

Our engineering team includes a technical lead with a PhD in ceramic engineering and 18 years of industrial high-temperature insulation experience, two senior process engineers with 10+ years each on fumed-silica pressing and opacifier dispersion, three application engineers with backgrounds in thermal-furnace design and refractory installation, and a quality-engineering group that runs the mill-test verification on every production lot. The technical team is the same group that responds to customer engineering queries — there is no intermediary between the customer's thermal engineer and our process engineer. For unusual specifications outside the standard matrix (high-density board above 280 kg/m³, very-thin panels below 10 mm, custom opacifier loading for higher-temperature service), the technical team runs the feasibility review, the lab-trial verification, and the production-trial scale-up before a commercial quotation is issued.

Anchor-tech track record

As the original equipment manufacturer, Anchor-tech owns the production process end to end. The fumed-silica master batch, the opacifier dispersion, the pressing cycle, the post-press drying, the cut-to-size operation, and the vacuum-panel lamination all happen on a single site under a single quality system. We do not buy pressed boards from a third party and re-sell them under our brand. We do not broker orders through a trading company. That vertical integration is what allows a thermal-conductivity question to be answered by the engineer who runs the pressing line, and what allows us to ship a custom-sized panel with the same mill-test-report traceability as a stock item. Our customers — procurement officers at steel mills, refractory installers at petrochemical complexes, OEM engineers at aerospace tier-1 suppliers — value that direct line of technical accountability.

Anchor-tech track record

The numbers we publish on our website and in our quotation letters come from our own production lots, measured on our own heat-flow meter, against our own lot traceability records. We do not paraphrase supplier datasheets. We do not publish "typical" thermal-conductivity numbers without an accompanying four-temperature-point verification. We do not round up — if a lot measures 0.024 W/(m·K) at 200 °C, we publish 0.024, not 0.020. For customers who require tighter lot-to-lot control, we run dedicated production batches with 100% inspection and a two-year sample-retention programme; the per-piece price uplift covers the additional QC time and is quoted explicitly in the commercial offer. We make the same commitment to data integrity for our overseas customers that we make for our domestic Chinese customers.

Anchor-tech has been pressing fumed-silica microporous insulation boards at our Guangzhou facility since 2014. Cumulative shipments since then exceed 18,000 m³ across standard board, laminated grades (PE film, aluminium foil, glass-fibre fabric), arc panels, custom-formed 3D parts, and powder grade. Approximately 40% of those shipments have been repeat orders from the same customer — a metric we track at the sales-record level because repeat business is the cleanest indicator that field performance has matched the design intent. Our annual production capacity is currently 6,000 m³ of finished board equivalent, with capacity expansion planned for the 2027 calendar year in response to growing European and Southeast Asian demand.
Our quality system is certified to ISO 9001:2015, covering design, production, and after-sales service. Microporous board products are tested to YB/T 4130-2005 (the Chinese metallurgical industry standard that defines microporous insulation board composition, density, thermal conductivity, and compressive-strength classes) and to EN 13501-1 fire classification A1 (non-combustible). Material compliance is documented per shipment with a REACH declaration, RoHS 2.0 third-party test certificate, and an asbestos-free declaration. CE marking is in place for the relevant product families. For special certifications required by specific industries or geographies — for example, GOST-R for Russia, INMETRO for Brazil, or BIS for India — we maintain a current register of supplementary certifications and can ship against them with appropriate lead time.
The company employs 200+ staff in total, of whom approximately 25 are engineers (R&D, process engineering, application engineering, and quality engineering) and 130 are production-floor operators. The Guangzhou factory operates three pressing lines dedicated to microporous board, two CNC cutting cells for arc panels and formed 3D parts, one granulation line for powder grade, and one vacuum-panel lamination cell for VIP products. Shift coverage is two-shift production with a quality-engineering presence on each shift. Application engineering and customer-facing technical support operate during single-shift business hours with after-hours WhatsApp coverage for urgent production queries. The technical lead holds a PhD in ceramic engineering and has 18 years of experience in industrial high-temperature insulation.
Export packaging follows a standard protocol: each panel is vacuum-sealed in PE film to prevent moisture ingress during transit, then stacked on export-grade wooden pallets or in wooden crates depending on size. Crates are heat-treated and ISPM-15 stamped for international phytosanitary compliance. Typical 20-foot container loading: 60–90 m³ of finished board depending on thickness. 40-foot high-cube container: 130–180 m³. Loading is supervised by our logistics team with photographic documentation. Each shipment carries a packing list, commercial invoice, mill-test report, REACH / RoHS / asbestos-free declarations, and any destination-specific certifications requested by the customer. We ship FOB Guangzhou as standard; CIF, CFR, and DAP terms are quoted on request.
Every production lot is sampled at three points — start, middle, and end of the batch run — and tested for density (target 220–280 kg/m³), thermal conductivity at 200 °C and 400 °C (target 0.022–0.025 W/(m·K) at 200 °C), dimensional tolerance (target ±2 mm length, ±1 mm thickness), and compressive strength at 10% deformation (target ≥0.35 MPa). The heat-flow meter used for thermal-conductivity verification is calibrated quarterly against a NIST-traceable reference standard. The results are compiled into a mill-test report that ships with each lot. We retain archived samples from every production batch for 24 months — if a customer reports a field issue, we can pull the archived lot sample and re-test against the customer’s installation condition. This level of traceability is uncommon in the industry and is one of the operational reasons we maintain our ISO 9001 certification rather than letting it lapse.
Our standard warranty is 12 months from ex-works dispatch against manufacturing defects. If a customer reports a field issue — cracked panel, off-spec thermal conductivity, premature service degradation — we ask for photographs, installation records, and lot number from the shipping documents. We then pull the archived sample for that lot and re-test in our lab. If the re-test confirms the customer’s report, we ship replacement material at our cost including freight and cover reasonable installation labour. If the re-test clears our product, we share the test data with the customer and jointly investigate the installation condition (joint staggering, pin pattern, vapour barrier integrity, moisture exposure during storage) to identify the root cause. We have honoured warranty claims on roughly 0.3% of shipments over the past five years — well below industry average — and our response time on a typical claim is 7–14 working days from initial report to resolution.
