Dimensions alone do not decide whether a product will work. We review the details that affect fit, appearance, assembly and repeat production.
We review the material, thickness, critical dimensions, hole positions, bending details, weld locations, surface finish and assembly interfaces against the current drawing or approved sample.
Key forming, welding, machining and appearance requirements are checked at the relevant production stages to reduce batch variation, rework and assembly problems.
Dimensions, appearance, assembly fit, quantity, labeling and packaging are reviewed before delivery so the order arrives ready for receiving and installation.
Feedback from customers who needed consistent parts, practical communication and a smoother route from sample approval to production.
The sheet metal parts arrived with clean edges, accurate dimensions and consistent finishing. Yishang reviewed the drawings before production, which made assembly much smoother.
Lorry Melon
We needed a custom metal enclosure for a new product. The team responded quickly, suggested practical material and finish options, and delivered samples that matched our requirements.
Steve Smith
Yishang understands OEM projects and keeps communication clear. They helped us move from sample testing to repeat orders with stable quality.
Elora
Our project required customized metal components in large quantities. Yishang provided inspection support and reliable production quality, helping us control cost and delivery risk.
krista
Yishang is a manufacturer with 26+ years of sheet metal experience and its own metal-production workshops. We also manage the additional processes required for multi-process projects.
Yes. One project team coordinates the drawings, samples, quality requirements, production stages and delivery plan across the required processes.
Yes. Samples can be produced and reviewed before repeat production is released.
Yes. We review drawing-based custom products, sample-based projects and suitable standard products for B2B purchasing requirements.
Yes. An NDA can be signed before you share confidential drawings, models or product information.
Send your current sketches, photos, samples or available files. We can review what information is still required before manufacturing begins.
Quality requirements are reviewed before production and checked at the relevant manufacturing, finishing, assembly and packing stages.
There is no single MOQ for every project. Samples are supported, while the practical production quantity depends on the material, process and tooling requirements.
Our quotation considers the complete manufacturing route, including material, tooling, secondary operations, inspection, assembly and packaging. The goal is to control the total project cost, not only the initial unit price.
Lead time depends on drawing readiness, tooling, material, sample approval, production quantity, finishing and assembly requirements. The schedule is confirmed after project review.
