FAQ
Q: How do I get a quote? What do I need to provide?
A: Send a message to our official email address at info@hansmat.com with a 2D/3D drawing/model of your product, your annual volume requirements, your material requirements, and your surface finish requirements. Our engineers will provide a quick assessment.
Q: What is the typical lead time from sample production to mass production?
A: For prototypes, delivery is typically 3-4 weeks after drawing confirmation, depending on the complexity of the product. The lead time for mass production is determined by order volume.
Q: Between gray cast iron, ductile iron, and aluminum alloy, how do I choose the best material for my application?
A: Gray cast iron (such as HT250): Offers optimal vibration damping and wear resistance, is cost-effective, and is suitable for most general-purpose gearboxes.
Ductile iron (such as QT500-7): Offers higher strength, toughness, and fatigue resistance, making it suitable for gearboxes subject to high shock loads and heavy loads.
Aluminum alloy (such as A356): Lightweight, with excellent heat dissipation and corrosion resistance, it is an ideal choice for weight-sensitive applications such as robotics and electric vehicles. Our engineers can provide you with professional material selection suggestions based on your specific working conditions (load, speed, environment).
Q: What shipping methods are available for the product?
A: Our shipping methods include ocean freight, air freight, and land transport. Shipping costs are typically provided to you in advance before the product is shipped.
