Frequently Asked Questions About Laboratory & Industrial Furnaces
Q: What types of furnaces does ACMAS / WEIBER manufacture?
A: ACMAS Technologies, under the WEIBER brand, manufactures a comprehensive range of laboratory and industrial furnaces including: muffle furnaces, tube furnaces, ashing furnaces, high-temperature furnaces (up to 1600°C), vacuum furnaces, brazing furnaces, retort furnaces, chamber furnaces, melting furnaces, pre-heating furnaces, air circulation furnaces, and clean room furnaces. We also manufacture application-specific furnaces for dental sintering, foundry heat treatment, glass processing, powder metallurgy, advanced ceramics, and thermal process technology. Standard and fully customized models are available.
Q: Can ACMAS manufacture a customized furnace to our exact specifications?
A: Yes, customized furnace manufacturing is one of our core capabilities. We engineer bespoke laboratory and industrial furnaces based on your technical specifications, including operating temperature range, chamber dimensions, heating rate, atmosphere type (air, inert gas, vacuum), loading configuration, control system requirements, and applicable quality standards. Share your specification with our team and we will provide a design proposal, dimensional drawings, and cost estimate within two to three working days.
Q: What is the maximum temperature range of your furnaces?
A: Our furnace range covers operating temperatures from 1100°C to 1600°C. Laboratory muffle and tube furnaces typically operate in the 1100°C–1400°C range, while our high-temperature and vacuum furnaces are designed for applications up to 1600°C. Custom furnaces can be engineered for specific temperature requirements on request.
Q: Are ACMAS furnaces certified to international standards?
A: Yes. Our Laboratory furnaces and Industrial furnaces are CE-marked, confirming compliance with European safety directives and making them suitable for export to Europe and acceptance by international quality systems. Our manufacturing facility operates under an ISO-certified quality management system. We can supply test certificates, calibration documentation, and performance validation records as required for pharmaceutical GMP, defence procurement, or export purposes.
Q: Which industries use your laboratory and industrial furnaces?
A: Our furnaces are used by research laboratories, pharmaceutical and biotech companies, ceramics and advanced materials manufacturers, foundries and metallurgy units, the dental industry (sintering of zirconia and CoCr alloys), aerospace and defence establishments (including DRDO and ISRO), renewable energy and electronics manufacturers, and glass fabrication plants. If your process involves controlled high-temperature treatment of any material, there is a WEIBER furnace designed for it.
Q: Do you export furnaces outside India?
A: Yes. ACMAS Technologies / WEIBER exports laboratory and industrial furnaces to over 30 countries across South Asia, Southeast Asia, the Middle East, Africa, and Europe. Our export team handles all aspects of packing, shipping documentation, customs compliance, and third-party inspection. International and export enquiries are welcome, contact us at info@acmasindia.com.
Q: What is the difference between a muffle furnace and a tube furnace?
A: A muffle furnace has a rectangular chamber with heating elements positioned around the outer walls, the sample is placed inside the "muffle" (the inner chamber), which shields it from direct contact with the heating elements and combustion gases. It is ideal for ashing, calcination, and heat treatment in air. A tube furnace has a cylindrical alumina or quartz tube as its working chamber, it is designed for processing samples in controlled atmospheres (inert gas, reducing gas, or vacuum) and is commonly used for synthesis, annealing under atmosphere, and chemical vapour deposition. ACMAS manufactures both types in a range of sizes and temperatures.
Q: How do I get a price quotation for a furnace from ACMAS?
A: You can request a quotation by filling in the enquiry form on our website, calling us at +91 11 47619688, or emailing info@acmasindia.com. For standard catalogue models, we typically respond within one business day. For customized furnaces, please share your technical specifications so our engineering team can provide an accurate design proposal and costing.
