Xiamen Yistar Precision Manufacturing Co.,Ltd

The stable operation of industrial machinery often lies in those unassuming plastic parts — our custom injection-molded gears, bearing retainers, casters, seals, pump bodies, guide rail sliders, junction boxes, and other core components. Using high-strength, wear-resistant, self-lubricating engineering plastics (such as POM, PA66, and PEEK) to replace metal, we reduce weight and lower noise. From transmission to sealing to mobility, we mold not just parts, but the confidence in long-term, trouble-free equipment operation.

You design the product, we bring it to life with precision plastic parts. In the consumer electronics sector, our custom injection molding capabilities cover products such as mobile phones, earphones, smart wearables, routers, and smart home devices — including enclosures, buttons, card trays, brackets, connector housings, internal structural parts, and more. Based on your drawings or samples, we can handle the entire process from mold design and injection molding to surface finishing (e.g., painting, IML, vacuum metallization). Our standard materials (PC, ABS, PC/ABS, PA, etc.) meet requirements for high dimensional accuracy, excellent aesthetics, and flame retardancy, ensuring stable quality and reliable lead times.

We have long been providing custom injection molded parts for the automotive industry, covering conventional interior trim parts (such as instrument panel bezels, door handles, air conditioning vents), exterior trim parts (such as bumper grilles, emblem bases, rearview mirror housings), and functional parts (such as clips, brackets, wire harness holders). Based on your drawings or samples, we can handle the entire process from mold design and injection molding to surface finishing (e.g., painting, plating, grain texture). We are highly experienced with common materials (ABS, PP, PC/ABS, etc.) and manufacturing processes, delivering stable quality and reliable lead times.

Your device designs, we bring to life with the most reliable plastic parts. In the medical field, our custom injection molding capabilities cover three major categories: consumables (e.g., syringe barrels, infusion connectors), diagnostics (e.g., assay kits, test tubes), and equipment components (e.g., monitor housings, surgical instrument handles). Based on your drawings or samples, we can handle the entire process from mold design and injection molding to cleanroom assembly. We use standard medical-grade materials (such as PP, PC, ABS, PEI, etc.) that meet biocompatibility requirements, ensuring high precision, contamination-free production, full traceability, and consistent, reliable quality.  

Big details in small objects — we bring quality to your everyday life. In the daily necessities and stationery sector, our custom injection molding capabilities cover packaging items (bottle caps, spray pump heads, food containers, electronic trays), household items (storage boxes, colanders, fresh-keeping box lids, clothes hangers and hooks), as well as stationery items (pen barrels and caps, stapler housings, rulers, correction tape casings, pencil cases), and more. Based on your drawings or samples, we can handle the entire process from mold design and injection molding to surface finishing (e.g., screen printing, hot stamping, texture engraving). Our standard materials (PP, PS, ABS, AS, PET, etc.) meet food contact safety standards (FDA, LFGB), as well as drop resistance and scratch resistance. We support high-volume, stable production with cost control and reliable lead times. From bottle caps to pen barrels — molding the small things that make daily life easier.
