Finding a reliable partner in the plastics industry requires more than just locating a factory with machinery. It requires finding a team that understands the intricate balance between material science, engineering precision, and scalable production. For over two decades, Heshan Zhongsheng Plastic Products Co., Ltd. has established itself as a cornerstone of manufacturing in the Greater Bay Area.
Since our inception in 2000, we have refined our capabilities to serve a diverse range of industries, from automotive and new energy to commercial kitchen supplies and luxury home appliances. Our facility, covering 5,000 square meters and housing over 30 advanced machines, is not just a production line—it is where your product concepts become tangible realities.
If you are evaluating potential partners for your next project, it is essential to understand the specific manufacturing technologies we employ. This guide breaks down our core processes, highlighting how we deliver quality, consistency, and customized solutions.

At the heart of our operations is our expertise in blow molding. This process is critical for creating hollow plastic parts and is the primary method we use to produce high-volume packaging solutions.
We specialize in Injection Blow Molding (IBM), a technique that offers superior precision compared to standard extrusion methods. This process is particularly vital for clients looking for a premier Plastic Bottles manufacturer capable of delivering consistent wall thickness and exact neck dimensions.
The IBM process involves three main stages:
Injection: Molten plastic is injected into a cavity to form a "preform" around a core rod. This creates the detailed neck finish.
Blowing: The preform is transferred to a blow mold, where air is blown through the core rod, expanding the plastic against the cold mold walls.
Ejection: Once cooled, the finished container is ejected.
For our clients, the benefits of this process are clear. It produces a flawless finish with no flash or seams, meaning no post-production trimming is required. This ensures that every bottle, whether for cosmetics or industrial chemicals, has a leak-proof seal and excellent optical properties.
We invite you to explore our specific capabilities in this area on our Blow Molding Plastic Bottles page.
While blow molding creates hollow containers, injection molding is our method of choice for solid, complex components. This process allows us to manufacture intricate parts with tight tolerances, such as ceiling fan blades, LED light covers, and functional hardware accessories.
Our injection molding services are designed for versatility. We can handle a wide array of thermoplastic resins, allowing us to tailor the durability, flexibility, and color of the final product to your exact specifications. Whether you need heat-resistant components for lighting or aerodynamic blades for cooling fans, our engineering team ensures the structural integrity of every unit.
To help you understand which process suits your product development needs, we have outlined the distinct applications of our two primary technologies below.
Feature | Injection Molding | Blow Molding (IBM) |
|---|---|---|
Product Type | Solid, complex 3D shapes | Hollow containers and vessels |
Typical Applications | Fan blades, LED covers, fixings | Shampoo bottles, chemical drums, food jars |
Key Advantage | High precision for intricate details | Seamless finish and uniform wall thickness |
Material Efficiency | Low waste, runners can be reground | Extremely low waste, no flash to trim |
Surface Finish | Smooth, textured, or matte options | High gloss or transparency available |
Manufacturing is rarely a "one size fits all" endeavor. That is why Heshan Zhongsheng offers comprehensive OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services. We do not just print your logo on existing stock; we can engineer entirely new solutions from the ground up.
Our customization process is streamlined to ensure transparency and speed:
Communication: We review your requirements, including styles and functional needs.
Drawing & Design: Our technical team creates or confirms detailed design drawings.
Prototyping: We offer sampling services to ensure the physical product matches your vision before mass production.
Production & QC: Using our automated machinery and rigorous testing protocols, we manufacture your order.
Logistics: We handle packaging and shipment to ensure safe delivery.
This full-cycle service allows us to support customized formulations, exclusive packaging designs, and high-quality branding for labeling.
A manufacturing process is only as good as the quality control that governs it. We operate under strict international standards to ensure safety and reliability.
ISO9001 Certification: This guarantees that our management systems meet global standards for quality assurance.
NSF Certification: Essential for clients in the food and water industries, ensuring our products meet strict public health standards.
Specialized Licenses: We hold specific licenses for producing food containers and chemical packaging, demonstrating our ability to handle sensitive and regulated materials safely.
Our facility includes a dedicated QC lab where products undergo rigorous testing for durability, leak resistance, and dimensional accuracy.
Heshan Zhongsheng Plastic Products Co., Ltd. is located in Taoyuan Town, Heshan City, within the Zhuxi Manufacturing Core Area of the Greater Bay Area. This strategic location provides us with excellent logistics and access to raw materials.
Yes, we support a free sampling service. You can provide us with pictures, samples, or specific parameters, and we will create a sample for your review. For specific details regarding shipping costs for samples, please contact our customer service team.
We serve a wide variety of industries. We have over 23 years of experience producing commercial kitchen supplies (cooperating with Franke Company) and 25 years of experience supplying fan blades and lampshades to luxury ceiling fan companies. We also produce packaging for cosmetics, automotive fluids, and new energy sectors.
Selecting the right manufacturer is about finding a company that values precision, safety, and partnership. With over two decades of experience, a 20,000 square meter facility, and a commitment to high-quality development, Heshan Zhongsheng is equipped to bring your product to market.
Whether you need a custom run of intricate injection-molded parts or a large-scale supply of blow-molded containers, our team is ready to assist.
