SuLian Precision Shengjuyuan Technology

About

We are a physical factory specializing in plastic modification, deeply rooted in the industry for many years, focusing solely on plastic materials without gimmicks or empty promises. Our factory has a complete modification production line and an independent R&D and testing center, covering raw material control, formula debugging, production processing, and full-item inspection before shipment—all completed in-house, demonstrating tangible strength. You are always welcome to visit our factory for on-site inspection. We mainly serve various plastic product manufacturers, with a core focus on customized material development: adjusting material strength, toughness, flame retardancy, weather resistance, heat resistance, anti-static properties, etc., according to the product's service environment; supporting special color compounding, new product sample production, small batch trial production, and import material localization to help factories solve material problems and control production costs. In addition to material business, we also provide small mold injection molding trial services. If customers have new small product molds, they can send them to our factory, and we will provide free injection molding trial and machine adjustment sampling to help quickly verify mold structure and material compatibility, saving back-and-forth effort and making early R&D and sampling more convenient. We also cooperate with rubber and plastics industry peers, offering raw material OEM manufacturing: supporting both toll manufacturing and full-service manufacturing modes, with confidential production to ensure no cross-sharing of customer resources, serving as a reliable backend factory to alleviate capacity shortages and limited R&D equipment of peers. We don't rely on fancy slogans; our long-term standing comes from: stable formulas, consistent batch quality, reliable delivery, and timely technical support. All modified materials undergo internal testing before shipment, ensuring quality and reducing production rework and after-sales issues. Whether you are a product factory requiring long-term material supply, a R&D customer needing customized modified materials or mold trial, or an industry peer requiring OEM manufacturing, we sincerely cooperate pragmatically, aiming for long-term stable win-win and handling each order down-to-earth.
