High-performance mechanical parts and customized assemblies manufactured to strict engineering tolerance guidelines.
Shenzhen Xinli Technology Co., Ltd. is located in Shenzhen and was established in 2016; it is a professional manufacturer of various auto parts, mechanical equipment parts, medical equipment parts, agricultural manned vehicles and drones Enterprise company of component products. We provide quality custom machining, manufacturing, and related solutions services to our customers with a legacy dating back more than 9 years.
By leveraging state-of-the-art automation and advanced injection molding techniques, we bridge the gap between initial prototyping and massive commercial scale-up. Our production workflows are designed to meet strict industrial specifications, ensuring structural integrity, thermal stability, and tight tolerance limits down to the micron scale.

Our factory is equipped with advanced Multi-Axis Turning Centers, CNC Machining stations, and professional Inspection apparatus to support high-precision medical, aerospace, and automotive components fabrication.
The performance of custom plastic injection components depends on matching the right polymer chemistry to the mechanical stresses the part will face. Engineered thermoplastics like PEEK (Polyetheretherketone), PPS (Polyphenylene Sulfide), and Ultem PEI (Polyetherimide) have replaced traditional alloys in aerospace, medical devices, and automotive engines. Managing polymer rheology—how the plastic flows when melted under heat and pressure—is essential for making high-quality parts.
During injection, the polymer melt undergoes non-Newtonian shear thinning. Our tooling engineers optimize gate locations and runner diameters to control shear rates, preventing thermal degradation and polymer chain scission. This careful control minimizes internal molded-in stress, preventing warping, dimensional changes, and environmental stress cracking (ESCR) when the parts are used in the field.
Replacing metal structural parts with reinforced plastics like PA66 and PBT to reduce vehicle weight, improve fuel and battery efficiency, and maintain impact strength in electric vehicles (EVs).
Manufacturing medical devices in cleanrooms using USP Class VI and FDA-compliant materials, ensuring bio-compatibility, chemical resistance, and sterilization stability (via Autoclave, Gamma, or EtO).
Producing wear-resistant gears, sliding components, and custom housings from POM, PEEK, and Nylon with self-lubricating additives for long service life in automated assembly plants.
Navigating international supply chains requires strict adherence to global engineering standards. At Shenzhen Xinli Technology Co., Ltd., we combine localized technical support with global delivery capabilities. Our operations comply with ISO 9001:2015 quality systems, and we provide full material traceability, including RoHS, REACH, and conflict-free mineral reporting.
Our DFM (Design for Manufacturability) reviews identify potential issues—such as uneven wall thicknesses, improper draft angles, or poor gate placements—before cutting steel. This proactive approach saves our clients time and reduces tooling costs.
The plastic injection industry is shifting toward smart manufacturing. Key updates to our technical roadmap include:
