Choosing the product quality and technical strength of a propane production factory is the core competitiveness.
1.The first one is key components and materials
1) Diaphragm: This is the “center” of the pressure regulator. Inquire about the material of the membrane (such as nylon cloth coated with nitrile rubber) and require it to be resistant to aging and propane corrosion.
2) Shell: Usually made of aluminum alloy die-casting. Check whether the surface treatment (such as baking paint, electroplating) is uniform and corrosion-resistant. The strength of the zinc alloy shell is poor and caution should be exercised.
3) Valve sealing: The durability of the sealing material directly affects the risk of leakage.
2.The second is the level of craftsmanship and manufacturing:
The precision of accessories: Whether the internal structure is finely processed directly affects the voltage stabilization accuracy and sealing performance.
Sealing test: Does the factory conduct a 100% air tightness test on each product? This is the most basic security guarantee.
Flow and pressure stability: The factory is required to provide test reports on key performance parameters such as inlet pressure, outlet pressure, closing pressure, rated flow, etc., and assess their stability.
Looking at the R&D capability of the factory again: Does the factory have a dedicated R&D team? Can we customize and develop according to your specific needs, such as non-standard flow rate, pressure, and interface size? This reflects the technical depth of the factory.
3. Production scale and supply capacity of the factory (based on commercial cooperation)
Capacity: What is the monthly or annual capacity? Can we meet your order volume requirements, especially during peak sales season to ensure timely supply.
Supply chain stability: Is the supply of raw materials stable? This is related to production cycle and cost control.
Inventory level: Is there a regular model of safety stock available to handle urgent orders?
4. Cost and price (balance of cost-effectiveness)
Quotation: Obtain detailed quotations and compare prices of different factories at the same quality level. Remember: you get what you pay for, low prices may mean cutting corners.
Minimum Order Quantity (MOQ): Is it suitable for your procurement plan? Does the factory accept small batch orders?
Payment method: Whether the payment terms are reasonable and flexible.
5. Service and Collaboration Experience (Soft Power)
Communication efficiency: Is the other party’s sales or technical support responsive, professional, and able to communicate smoothly in your language (such as English)?
After sales service: Is there a comprehensive after-sales policy? How to deal with quality issues (return, exchange, compensation)?
Sample provision: Would you be willing to provide samples for your testing? This is the most direct way to verify the quality of its products.
Collaboration case: Do you have any experience working with well-known brands or large enterprises? This can serve as evidence of its reliability.
DERKIA company requires all of the above conditions and welcomes overseas merchants to visit the factory and place orders.
