Q1: How do I place an order for collaboration?
+
We provide a bill of materials, and we will promptly prepare a quotation. After the quotation and delivery schedule are confirmed, we will sign a sales contract. Upon receipt of payment, we will arrange production and shipment; for international trade, trade terms can be negotiated.
Q2: How should I handle a defective item upon receipt?
+
Please conduct a spot check upon receipt of the goods. If the issue is indeed due to a manufacturing defect on our part, we will arrange for a replacement or a credit toward the purchase price after confirming the quantity.
Q3: Can it be packaged in neutral, unbranded packaging for export?
+
We support neutral packaging without our brand markings, meeting the needs of traders and original equipment manufacturers for export‑ready components.
Q4: Do you support OEM laser marking and customer branding?
+
Support available: laser engraving of customer logos and model numbers on connectors and vibrator housings, with corresponding minimum order quantities.
Q5: Can the price be negotiated for large purchase volumes?
+
Prices are calculated based on a comprehensive assessment of purchase quantity, specifications, packaging, and whether customization is required; the larger the order volume, the more competitive the unit price.
Q6: Could you please provide a sample? Is there a charge for the sample?
+
Samples are available; a small sample fee will be charged, which will be refunded upon placing a bulk order. Shipping costs are borne by the customer.
Q7: How do you select a pneumatic vibrator, and what excitation force should I choose?
+
Select the appropriate model based on hopper volume, material specific gravity, and material state (powder or granules), and provide operating condition parameters. Our technical team can help match the right model to prevent oversizing or undersizing.
Q8: How do you select between PU air hoses and PA nylon air hoses?
+
For standard indoor automation applications, PU tubing is the preferred choice due to its excellent flexibility and ease of wiring. For high‑temperature, outdoor, high‑friction, or heavily oil‑contaminated environments, PA nylon tubing is recommended. We can provide a selection guide to help you make the right match.
Q9: What causes air leaks at joints, and how can we ensure they remain airtight?
+
Common causes of air leakage include tolerances in the tubing’s outer diameter, damage to the sealing ring, unsealed threads, and incomplete insertion of the air hose. We conduct 100% airtightness inspections on finished products and rigorously control tubing‑fitting tolerances; each unit is shipped with a selection and installation guide to minimize the risk of on‑site leaks.
Q10: How long is the product warranty period?
+
Under normal operating conditions, the standard product is covered by a 12-month warranty; however, warranty does not apply to damage caused by improper installation or operation under adverse conditions exceeding specified parameters.
Q11: What is your minimum order quantity (MOQ)?
+
Standard off-the-shelf products have no strict MOQ and are available for small‑batch sampling; neutral packaging for international trade and OEM laser marking both have minimum order requirements, which will be confirmed on a per‑product‑model basis.
Q12: What is the factory’s production capacity, and what is the lead time for bulk orders?
+
Standard pneumatic fittings have a daily production capacity of tens of thousands of units; standard in-stock orders are delivered within 3–7 days; bulk orders take 7–15 days; for non‑standard customizations, the exact lead time will be provided after a process‑based assessment.
Q13: Are you a manufacturing factory or a trader?
+
We are a physical manufacturing facility with fully integrated workshops for machining, assembly, and quality inspection. We independently produce pneumatic fittings, PU/PA air hoses, silencers, and pneumatic vibrators, and we offer OEM/ODM services. On-site factory inspections are welcome by appointment.
