Exhibits
The core manufacturing processes include turning and milling with turret-type multitasking machines, vertical milling, high-speed engraving, surface treatment, and electroless nickel plating for stable precision-part production. Electroless nickel plating is identified for complex geometrical workpieces that require uniform film thickness. Casting and forging services are available for complex precision parts such as machinery parts, automotive machining parts, medical parts, and food-machinery parts. The forging process applies pressure to metal so that it plastically deforms into the required object shape. The casting process melts metal into a liquid state and forms casting parts according to a mold. Sharp-eyed Precision Parts Co., Ltd. combines casting and forging processing with OEM precision-forging capability and customized machining. The company works to shorten mold-development cycles, reduce mold-manufacturing cost, produce varied component types, and has developed more than thousands of mold items. A post-process surface-treatment factory handles surface treatment for different types of CNC-machined parts, with electroless nickel plating identified as the main technology. The post-treatment team also performs anodizing according to the characteristics of the product. Metal passivation is used to increase oxide-layer thickness so metal objects gain protection against corrosion and abrasion and customized metal parts can have longer service life. Other plating processes include gold plating, chrome plating, galvanization plating, nickel plating, and plastic plating for hardness, wear resistance, and corrosion protection. Surface-finishing options also include laser engraving, sand blasting, polishing, and nano-painting to produce smoother and more refined part surfaces. The company describes these post-processing technologies as supporting metal parts used in harsh environments. For brass inserts, the company manufactures standard metal inserts as well as custom brass insert nuts and brass turned parts. Its precision-machining experience is used to provide samples according to customer needs, with R&D suggestions intended to accelerate new-product development. Precision brass-insert work can cover prompt sample making and mass production, including custom threaded inserts and various machined parts. Annual production for brass inserts is stated at about 150 million pieces. Brass-insert designs include flange-head, symmetrical, and full diamond knurl types, with custom designs offered across a wide range of sizes, insert types, and specifications. Brass nuts offer corrosion resistance, high-temperature resistance, and strong ductility, and the company supplies multiple nut types and screw specifications in metric and imperial systems. Brass-nut processing parts are produced according to ISO / TS 16949 production standards. Automotive machining covers parts used for locking and pivoting functions, with processing methods that include turning, forging, rolling, heat treatment, and electroplating. OEM automotive parts include auto screws, car nuts, suspension bushings, and other fasteners. CNC precision machining provides greater precision and adaptability than traditional manufacturing, including multi-axis processing for complex automotive parts. The automotive workflow can extend from die-casting through component production, alongside car casting, car forging, mechanical processing, and post-processing services. The automotive quality system focuses on improving process quality, identifying production and supply-chain problems and risks, removing their causes, and checking corrective and preventive measures. Automotive parts and accessories include cooling-system parts and accessories, skylight parts, trunk parts, and rear-mirror parts. Named automotive customers include TOYOTA, MITSUBISHI MOTORS, NISSAN, MAZDA, HONDA, and Harley Locomotive for commissioned precision-parts processing. The company's foundry and machining products are applied in the automotive, bicycle, electronic 3C, communication-equipment, and medical industries. For bicycle applications, it supplies investment casting and forging solutions for complex parts and turning and milling services ranging from simple to complex bicycle parts. For electronics manufacturers, the company offers customized processing and manufacturing with CNC milling and turning capabilities for OEM machining requirements. For communication equipment, precision CNC machining is used for aluminum body structures in mobile-phone applications. For medical use, Sharp-eyed Precision Parts Co., Ltd. supplies components for surgical instruments, medical-device components, and other precision medical parts. Medical parts are also machined in a temperature-controlled facility. A Japanese high-speed compact multitasking machine acquired in 2017 uses double spindles and dual powered turrets for turning and milling work. Its driven-tool motor is specified at 7.1/2.2kw with maximum 16N-m, and the driven-tool speed is 6,000 rpm. The machine's 12-angle tool stations support 48(24+24) lathe tools or 24(12+12) milling tools, while facing left and right spindles can process simultaneously. The upper and lower turrets provide Y-axis function with a movable stroke of 62mm (±32mm) and use a 12-corner 24-tool seat configuration. Machine dimensions are 2,780mm(L)ｘ2,070mm(W)ｘ2,060mm(H), maximum machining diameter/length is 200mm/570mm, and round-bar processing capacity is 51mm. Other listed specifications include L,R:162mm(6") clip size, 5,000min-1 spindle speed, 11/7.5 kW spindle motor power, 6,000min-1 rotating-tool speed, and 7,400kg machine weight. The factory's four main manufacturing processes are turning and milling with a turret-type super multitasking machine, milling, high-speed engraving, and electroless nickel plating. The vertical milling machine is specified with optional spindle speed of 12,000 rpm, 18.5KW power, and travel of X:1020mm, Y:520mm, and Z:540mm. Its milling setup uses a bi-directional random-rotation magazine, a 24T automatic tool-changing system extendable to 40T when required, and axial feeding by high-precision ball screw. The high-speed engraving machine uses a 60,000-PRM built-in high-speed spindle, tool ATC with a machine-coordinate tool system, a high-rigidity casting structure, and three-axis rapid displacement up to 20m/min. A post-process surface-treatment plant in Changbin Industrial Park, Taiwan is identified for the electroless-nickel process, where reduced nickel deposits on a catalytically active substrate surface. The electroless-nickel sequence includes Step 1 thermal degreasing, Step 2 ultrasonic cleaning, and Step 3 electroless nickel. CNC machining materials include copper grades C1100, C2600, C3604, C6801, and C6802; iron grades 1144, 12L14, and 1215; aluminum grades 2011, 6061, 6082, and 7075; and stainless-steel grades SUS303, SUS304, SUS316, SUS416, SUS420, and SUS430. For sheet-metal fasteners, the production line covers raw-material processing, cold heading, thread rolling, thread testing, heat treatment, screw-tension testing, and screw surface treatment. CNC machining can process precision parts in metal or other materials, with the company describing finer cutting-surface tolerances than traditional lathes. Precision parts can be produced according to customer drawings or requirements using CNC turning and milling technology. The same processing-service range includes investment casting and forging for complex machinery, automotive, medical, and food-machinery parts. It also includes finishing operations in the company's post-process surface-treatment factory, where electroless nickel plating, anodizing, and passivation are applied to CNC-machined parts according to product requirements. The product scope also includes aerospace high-strength components, medical surgery micro-components, and EV (Electric Vehicle) precision parts alongside CNC precision machining.
