Frequently Asked Questions
Q: What is your MOQ?
A: Generally, there is no minimum order quantity; it depends on the specific size and working conditions.
Q: Can you provide samples? Any charges?
A: Samples can be provided. Small samples are free if in stock; large samples or those not in stock will incur a charge (which can be deducted from the order price).
Q: Can you produce according to drawings?
A: Yes, we can customize production according to customer drawings and requirements.
Q: What is the working principle of the Pure Tungsten Heating Element?
A: The element heats a tungsten filament with an electric current, utilizing its high resistance to generate heat, achieving rapid and uniform heating.
Q: What precautions should be taken during installation?
A: During installation, keep the element straight and ensure the base is securely fixed to avoid localized overheating and concentrated mechanical stress.
Q: How to clean the element surface?
A: It can be wiped with a dry cloth or cleaned with mild alcohol, avoiding scratches that may affect heating performance.
Q: How resistant is the element to oxidation?
A: The pure tungsten material surface is polished or chemically treated, allowing for long-term use in a vacuum or inert gas environment.
Q: What precautions should be taken when transporting the element?
A: Avoid impacts and moisture; packaging must protect the element surface from oxidation.
