As a dedicated manufacturer, we provide plastic components and are not a trading company.





Plastic holders are designed with various structural configurations to meet different functional requirements:
Snap-fit holders: Enable quick assembly and disassembly, ideal for applications requiring frequent access or adjustments.
Adjustable holders: Feature mechanisms for variable positioning, suitable for accommodating different sizes or orientations.
Mounting brackets: Provide secure attachment to surfaces, commonly used in electronics and automotive applications.
Clamping holders: Offer a firm grip, often used for securing pipes, cables, or tools.
Multi-component holders: Combine different materials or features for enhanced functionality, such as vibration dampening or insulation.
Each structure is designed to optimize load-bearing capacity, stability, and ease of use.
Selecting the appropriate plastic material is essential for ensuring the holder's durability and performance. Common materials include:
ABS (Acrylonitrile Butadiene Styrene): Known for its high impact resistance and rigidity, suitable for robust holders.
PC (Polycarbonate): Offers excellent transparency and high impact strength, ideal for holders requiring visual inspection.
PA (Polyamide, Nylon): Exhibits high tensile strength and heat resistance, suitable for demanding environments.
PP (Polypropylene): Provides good chemical resistance and flexibility, commonly used for general-purpose holders.
PVC (Polyvinyl Chloride): Often used for pipe and cable holders, offering good chemical resistance and durability.
TPE (Thermoplastic Elastomer): Offers a rubber-like flexibility and grip, ideal for tool and equipment holders.
We assist you in selecting the best material based on mechanical requirements, environmental factors, and the desired lifespan of the holder.
Plastic holders are used across numerous industries for diverse applications:
Electronics: Securing circuit boards, connectors, and components in electronic devices.
Automotive: Mounting sensors, cables, and interior trim components.
Construction: Supporting pipes, conduits, and cables in buildings and infrastructure.
Medical: Holding tubing, sensors, and devices in medical equipment.
Household Appliances: Component assembly, wire management, and structural support.
Retail: Displaying products, organizing shelves, and mounting signage.
Our custom-designed plastic holders ensure reliable support and ease of integration into your specific application.
The Injection Molding Process Explained
Design: Use CAD software to create the holder design, optimizing it for material flow and cooling.
Mold Creation: Precision machine the mold from steel or aluminum, ensuring tight tolerances and a high surface finish.
Injection: Inject molten plastic into the mold cavity under high pressure.
Cooling: Allow the plastic to cool and solidify within the mold.
Ejection: Open the mold and eject the finished plastic holder.
Finishing: Remove excess material and perform any necessary post-processing, such as surface treatments or assembly.
Advantages of Our Injection Molding Services
Custom Tooling: We design and manufacture molds tailored to your specific holder design and production volume.
Material Selection: Our team provides expertise in selecting the optimal plastic material for your application.
Quality Control: We maintain rigorous quality control throughout the injection molding process to ensure consistent part quality.
Assembly Services: We offer optional assembly services, providing complete or semi-complete holder components.
Design Support: We provide design assistance to optimize your holder for manufacturability and performance.
Optimizing Mold Temperature
Maintaining optimal mold temperature is crucial during injection molding, influencing the quality, shrinkage, and cycle time of the plastic holders. Effective mold temperature control ensures consistent part quality and reduces defects.
