Our Production Capacity & Injection‑Molding Workshop
Foshan Starmax Plastic Products Co., Ltd. owns a complete injection‑molding workshop for door and window plastic accessories production. Equipped with multiple modern injection molding machines, our workshop covers the full manufacturing workflow from raw material feeding, injection forming, product demolding to post‑processing and inspection.
High‑performance injection machines ensure stable molding for various parts including drainage covers, corner brackets, weather‑strip accessories and vent plates. We strictly control key parameters such as injection pressure, temperature and cooling time. Consistent parameter setting is critical to avoid product deformation, shrinkage and burrs, guarantee uniform dimension for each batch of finished goods.
Our production process follows standardized operation specifications. Before mass production, new moulds will go through trial injection and sample confirmation. Once samples are approved by customers, formal bulk production starts. During continuous production, our operators conduct periodic spot‑checks on appearance, size and toughness of parts. Defective items will be picked out immediately to prevent non‑qualified products flowing into next procedure.
Besides injection molding, our workshop also supports in‑house mould maintenance and simple mould modification service. When customers require OEM custom plastic accessories, our team can adjust mould structure accordingly. Raw materials are stored in dedicated warehouse with moisture‑proof treatment to prevent material performance degradation caused by damp environment.
Finished products will be delivered to QC station for comprehensive inspection before packing and shipment. Combining automated equipment and manual quality monitoring, our workshop balances production output and product reliability. With flexible production capacity, we can handle both small‑batch trial orders and large‑volume bulk orders for global buyers. Starmax keeps optimizing production efficiency and quality control system, striving to deliver dependable window‑door plastic accessories to worldwide clients.
OEM & ODM Plastic Window and Door Accessories — Custom Solutions from Starmax
Foshan Starmax Plastic Products Co., Ltd. provides OEM and ODM solutions for plastic accessories used in aluminum windows and doors. We work with window and door manufacturers, accessory distributors, and brands to develop components that match their product requirements. Whether you need accessories manufactured according to an existing drawing or support in developing a new design, we welcome the opportunity to discuss your project.
Our product range includes window drainage caps, glass setting blocks, sliding window buffer blocks, anti-lift blocks, window corner protectors, door handle covers, and aluminum profile end caps. These components serve different purposes during assembly, installation, everyday use, and transportation. Through our OEM and ODM services, customers can explore accessory solutions tailored to their aluminum profile systems, production processes, and market needs.
For OEM projects, customers can provide drawings, physical samples, dimensions, and material specifications for review. We focus on understanding the details that affect compatibility, including fitting positions, connection structures, clearances, and overall shape. Confirming these requirements early creates a clear basis for discussing tooling, samples, and production. Our goal is to help customers turn established product specifications into suitable manufactured components.
Our ODM service supports customers who have an application requirement but need assistance developing the accessory itself. You may be looking for a drainage cap that fits a particular opening, a glass setting block with specific dimensions, or a protective component designed around your window frame. By discussing the intended function and reviewing the relevant profile, we can explore design options and identify details that require further evaluation.
Customization may involve dimensions, shape, material, color, surface appearance, and packaging, depending on the product and project requirements. Different accessories need different considerations. A glass setting block must suit its intended support position, while a window corner protector needs to match the frame and packaging arrangement. We review these factors individually so that customization remains closely connected to the component’s actual use.
Sample evaluation is an important step in developing custom window and door accessories. Before confirming a design for production, customers can assess fitting, assembly, appearance, and function within their own systems. Feedback from this evaluation helps identify where adjustments may be needed. Clear communication throughout the process supports better decisions and helps both sides understand the approved specifications.
We also welcome discussions about branding and packaging requirements for distributors and private-label customers. Product identification, packing quantities, and presentation can be reviewed alongside the accessory specifications. Establishing these details in advance helps align the finished order with the customer’s handling, distribution, and sales needs.
At Starmax, we believe successful OEM and ODM cooperation starts with a clear understanding of your application. We value detailed inquiries and practical feedback, whether your project involves an existing accessory or a new product concept. Our approach is to communicate requirements carefully and build cooperation around confirmed details.

R&D for Plastic Window and Door Accessories — From Product Ideas to Practical Solutions
At Foshan Starmax Plastic Products Co., Ltd., research and development focuses on the details that make plastic accessories suitable for aluminum windows and doors. From the shape of a drainage cap to the fitting position of a buffer block, each component needs to serve a clear purpose. Our development approach starts with understanding how customers manufacture, assemble, install, and use their window and door systems.
Our product range includes window drainage caps, glass setting blocks, sliding window buffer blocks, anti-lift blocks, window corner protectors, door handle covers, and aluminum profile end caps. Each category presents different design considerations. We approach product development by reviewing the accessory’s intended function, its relationship with the aluminum profile, and the requirements of the customer’s application.
Compatibility is a central part of this process. Aluminum profiles vary in dimensions, openings, grooves, and connection details, so accessories must be evaluated against the systems they are intended to fit. Customer drawings, measurements, and physical samples provide valuable information. By reviewing these references, we can identify important fitting dimensions and discuss where design adjustments may be required.
CAD design helps translate product requirements into structures that can be reviewed and refined. It allows us to consider dimensions, wall thickness, positioning features, and overall geometry before moving forward with tooling discussions. Clear drawings also support communication with customers, giving both sides a more precise understanding of the proposed component and the specifications that need confirmation.
Material selection is another important consideration in developing plastic window and door accessories. The intended use, required flexibility or rigidity, appearance, and manufacturing process all influence the discussion. Rather than applying the same material requirements to every product, we consider the needs of each component. Any specific performance expectations should be defined and evaluated as part of the project.
Our R&D work also considers how a design can be manufactured through injection molding. Product geometry, tooling requirements, and dimensional consistency need attention during development. Reviewing these factors early helps identify potential production difficulties and supports practical design decisions. The aim is to develop components that balance their intended function with suitable manufacturing methods.
Sample evaluation connects the design process with real applications. Customers can assess whether a component fits the profile, supports assembly, and performs its intended role within their system. Feedback may lead to changes in dimensions, shape, or other details. This exchange helps guide development toward an agreed design rather than relying on appearance alone.
We also see customer feedback as a starting point for product improvement. Questions raised during production, installation, packaging, or transportation can reveal opportunities to refine an accessory. A clearer understanding of these everyday challenges helps us focus development efforts on changes that have practical value for manufacturers and distributors.
