WHY CHOOSE US
FAQS
Q1. Can you accommodate custom specifications?
A: Yes, we can modify crucibles to meet your special technical data or drawings.
Q2. What is your sample policy?
A: We can provide samples at a special price, but customers are responsible for the sample and courier costs.
Q3. Do you test all products prior to delivery?
A: Yes, we perform 100% testing before delivery to ensure product quality.
Q4: How do you establish and maintain long-term business relationships?
A: We prioritize quality and competitive pricing to ensure our customers benefit. We also value every customer as a friend and conduct business with honesty and integrity, regardless of their origin. Effective communication, after-sales support, and customer feedback are also key to maintaining a strong and lasting relationship.
Q5: How to prevent crucible cracking?
Never charge cold material into a hot crucible (max ΔT < 400°C).
Cooling rate after melting < 200°C/hour.
Use dedicated crucible tongs (avoid mechanical impact).
Q6: What is the minimum order quantity (MOQ)?
Standard Models: 1 piece (samples available).
Custom Designs: 10 pieces (CAD drawings required).
Q7:How can we guarantee quality?
We guarantee quality through our process of always creating a pre-production sample before mass production and conducting a final inspection before shipment.
Q8:What is your production capacity and delivery time?
Our production capacity and delivery time depend on the specific products and quantities ordered. We work closely with our customers to understand their needs and provide them with accurate delivery estimates.
Q9:Is there a minimum purchase requirement I need to meet when ordering your products?
