Does KGL provide laser marking or part number engraving for finished parts?

Yes. For areas such as grounding contact surfaces, threaded holes, and high-precision mating surfaces where anodizing or coating needs to be avoided, KGL can use high-temperature-resistant masking tape or customized plugs for localized masking. For areas that require further machining after anodizing, secondary precision CNC machining can also be performed to meet conductivity and assembly requirements.

KGL provides anodizing, polishing, grinding, and coating services for custom precision parts. Its surface-treatment range also includes chromate conversion coating, sandblasting, blackening, wire drawing, electroplating, electrophoretic coating, and painting. These services can be combined with CNC milling, CNC turning, turn-milling machining, drilling, tapping, grinding, multi-axis machining, and wire EDM for custom component production.

For thin-wall and easily deformed structures, KGL uses multiple stress-relief processes, such as annealing, and uses vacuum suction or dedicated modular fixtures for workholding. During machining, high-speed cutting and small depth-of-cut parameters are used to help control part deformation.

For deep-hole structures, KGL can use internal-coolant deep-hole drilling and EDM equipment to control dimensional accuracy and geometric form. KGL has over 80 high-end CNC machines, including 3-, 4-, and 5-axis machining centers, CNC turning and milling equipment, grinding machines, gantry machining centers, and wire EDM equipment. The company provides milling, turning, turn-milling, multi-axis machining, precision grinding, and wire EDM services.

For scratch-prone, fragile, precision metal, or plastic parts, KGL can provide customized protective packaging, including individual blister trays, anti-static bags, vacuum packaging, custom EPE foam inserts, and high-density foam dividers. These packaging methods are suitable for precision components after CNC machining, as well as medical device components, aerospace components, robot parts, optical sensor components, housings, and enclosures that require international transportation.

Before shipment, KGL checks the packaging method, part quantity, labels, and anti-rust oil application where required. Qualified parts are protected in packaging after final inspection, which includes checks of dimensional tolerances, appearance, and surface treatment. Packaging-related inspection is part of the company’s delivery process.

Yes. KGL places strong importance on protecting customer intellectual property and can sign a standard confidentiality agreement provided by either the customer or KGL before a project begins.

Customers can provide part drawings, 3D models, samples, process requirements, and other project information for custom precision component manufacturing discussions.

KGL provides services ranging from single-piece customization and rapid prototyping to batch production, covering CNC milling, turning, mill-turn machining, multi-axis machining, grinding, wire EDM, and other supporting processes.

An NDA can provide a basis for cooperation on projects involving medical device components, aerospace components, humanoid robot components, optical sensor components, and housing-related parts.

Yes. KGL implements strict batch management for incoming raw materials. For projects with specific requirements, KGL can provide Material Test Reports (MTRs), heat or batch number records, and spectrographic analysis reports to support material traceability.

For aerospace projects, KGL can also maintain records of material batches, machining parameters, and operator information. Its quality system includes incoming inspection, 100% first-piece inspection, in-process checks, sampling, and final full inspection.

KGL is certified to ISO 9001:2015, ISO 13485:2016, and BV AS9100D. Related reports, including inspection data, supplier material certificates, and surface-treatment test reports, are organized and archived after shipment for future batch inquiries.

KGL has experience handling international shipments for CNC machined parts and works with DHL, FedEx, UPS, as well as sea and air freight forwarders. Orders can be shipped from single-piece samples to small- and medium-volume production runs. Once the parts have passed final inspection, they are packaged and prepared for delivery.

For orders going to a designated warehouse, DDP shipping is available. This can cover export declaration, import customs clearance, duties, and taxes, with the shipment delivered to the warehouse specified by the customer.

Before dispatch, the packaging, part quantity, labels, and rust-prevention requirements are checked against the order. Depending on the type of part, including precision metal components, plastic parts, and surface-treated parts, packaging may include individual blister trays, anti-static bags, vacuum packaging, custom EPE foam inserts, or high-density foam dividers to help protect the parts during transportation.
