Manufacturing Information Guide
Optimise your custom parts projects with QZSD Machinery by accessing comprehensive manufacturing resources covering material selection, design specifications, quality standards and production processes.
To process your custom order efficiently, we need detailed specifications including technical drawings (CAD files preferred), material requirements, surface treatment preferences, quantity needed, application details, tolerance requirements, and delivery timeline. Providing clear information helps us understand your exact needs and reduces back-and-forth communication. For complex customizations, our engineering team can schedule a consultation to discuss your project requirements in detail and suggest optimal manufacturing approaches.
Our minimum order quantity varies based on part complexity, material type, and manufacturing process. For standard custom bearings, bolts, and nuts, we typically require an MOQ of 200 pieces. For highly specialized components, we may accept smaller quantities. Contact our sales team with your specifications for precise MOQ information related to your specific requirements.
The customization timeline depends on design complexity, material availability, and order volume. After receiving complete specifications, we provide a 3-5 day turnaround for quotes. Production lead times range from 15-30 days for standard customizations and 30-45 days for complex projects. Rush orders may be accommodated based on our production schedule and capacity.
Yes, we offer sample production before full-scale manufacturing. Sample costs vary based on complexity and are often credited toward your final order. Most custom samples are ready within 7-12 days after design approval. We encourage sample testing to verify fit, function, and quality before proceeding with large production runs.
We work with a wide range of materials including carbon steel, stainless steel (304, 316, 440C), alloy steel, brass, bronze, aluminum alloys, and various engineering plastics. All materials meet international quality standards. Our engineering team can recommend the most suitable material based on your application requirements, environmental conditions, and budget constraints.
Yes, all custom parts undergo rigorous quality testing before shipment. We provide material certificates, dimensional inspection reports, and when requested, specific testing documentation such as hardness, tensile strength, or chemical composition analysis. Our facility maintains ISO 9001 certification, and we can meet industry-specific standards based on your requirements.
Yes, we regularly modify standard bearings, bolts, and nuts to meet specialized needs. Common modifications include dimensional adjustments, material upgrades, surface treatments, tolerance improvements, and adding features like grooves or holes. This approach often saves time and cost compared to fully custom designs while still meeting your specific requirements.
Pricing for custom parts is determined by material costs, manufacturing complexity, volume, surface treatments, and quality requirements. We provide transparent quotes with no hidden fees. For long-term partnerships, we offer volume discounts and can develop cost-reduction strategies. All quotes include material, labor, quality control, and basic packaging costs.
Testimonials
Find out why our global clients trust us with their precision parts requirements by reading authentic feedback about our quality, reliability, customisation capabilities and exceptional service.
Working with QZSD Machinery transformed our production line efficiency. Their custom stainless steel bearings outlasted our previous supplier’s by 40%. We initially ordered 2,000 units for our food processing equipment, and have since placed three additional orders. Their engineering team suggested material modifications that solved our corrosion issues completely.
QZSD provided custom high-tensile bolts for our construction equipment that withstand extreme pressure conditions. After six months of field testing across 12 different sites, zero failures were reported. Their technical team worked closely with our engineers to develop the perfect alloy composition. Delivery was consistently on schedule across multiple orders totaling 50,000+ units.
As an industrial equipment importer serving European markets, quality certification is critical. QZSD’s documentation package exceeds our requirements, with comprehensive material testing reports for each batch. Their custom bearing assemblies reduced our assembly time by 22% while maintaining strict dimensional tolerances of ±0.01mm. Reliability has been outstanding across our 15,000 unit order.
The specialized bronze bushings QZSD manufactured for our marine equipment operate flawlessly in saltwater environments. After switching to their custom solutions, maintenance intervals increased from 6 months to 18 months. Their engineering team suggested a proprietary surface treatment that significantly improved corrosion resistance while staying within our budget constraints.
We needed custom-threaded nuts for a specialized agricultural machinery line with extremely tight deadlines. QZSD delivered 8,000 precision components two weeks ahead of schedule, with 100% quality compliance. Their technical support during implementation solved installation challenges we hadn’t anticipated. Three years later, we haven’t had a single field failure.
QZSD’s custom bearing solutions for our textile machinery reduced operational noise by 15 decibels while extending maintenance intervals. Their engineering team analyzed our specific requirements and recommended a hybrid ceramic design that outperformed expectations. Despite complex specifications, they maintained consistent quality across our order of 12,500 units over multiple shipments.
