Advantages of Over Molding Service

Over Molding Service enhances product durability, functionality, and aesthetics while reducing manufacturing costs. It combines materials to create composite parts with improved shock resistance, appealing finishes, and integral features like soft grips, contributing to streamlined production and heightened product performance.

Advantages	Key Features
Enhanced Durability	Over Molding enhances product durability by bonding different materials together, creating a protective layer that resists shock, vibration, and environmental factors effectively. It ensures longevity and robustness, essential for demanding applications.
Improved Aesthetics	This technique significantly enhances the visual appeal of products, integrating multiple textures and colors for a premium finish without additional painting or coating. It achieves a seamless and attractive look critical for consumer satisfaction.
Increased Functionality	Over Molding adds essential functional features such as soft-touch grips, anti-slip surfaces, and watertight seals. These enhancements improve user interaction, safety, and product usability, making it ideal for diverse applications.
Cost Efficiency	Over Molding reduces both assembly time and costs by directly molding additional material layers onto base parts. This method eliminates the need for subsequent assembly steps, lowering labor and production costs significantly.

Custom Parts Surface Finishing Available

Our Surface Treatment Service offers specialized finishes for custom parts, enhancing durability, aesthetics, and performance. We provide a range of processes, including Electroplating, Anodizing, Powder Coating, and Thermal Barrier Coatings, tailored to improve corrosion resistance, wear properties, and visual appeal of metal and plastic components across industries.

Design Elements	Standard/Specifications	Reasons
Max Size	250 mm x 250 mm x 250 mm	Limiting the overall size ensures uniform cooling of both the substrate and the overmold material, preventing separation or warpage during the molding process.
Min Size	4 mm x 4 mm x 4 mm	The minimum size is dictated by the need for adequate surface area to achieve a strong bond between the substrate and the overmold, while maintaining overall part integrity.
Min Overmold Thickness	0.6 mm	A minimum overmold thickness ensures sufficient material coverage for durable bonding and consistent surface quality over the substrate.
Max Overmold Thickness	8 mm	Excessively thick overmold layers can lead to uneven curing and stress differentials, which may result in delamination or reduced flexibility.
Min Net Weight	1 gram	Ensures even the smallest parts have sufficient material for proper overmold adhesion and overall durability.
Cost-effective Max Weight	120 grams	Balances material usage with production cost, ensuring efficient molding without excessive material waste.
Max Net Weight	4 kg	The upper weight limit maintains process control and ensures consistent bonding between the substrate and the overmold material.
Precision Range	+/- 1% to +/- 2%	This range reflects the achievable dimensional accuracy for overmolded parts, considering the dual-material process and thermal variations.
Min Tolerance	±0.01 inch	Ensures proper fit and function of overmolded components, especially when secondary assembly is involved.
Cost-effective MOQ	10,000 units	High-volume production is required to amortize tooling costs and achieve economies of scale in overmolding.
Max Efficiency	95% material utilization	Indicates efficient use of raw materials in overmolding, minimizing waste while ensuring optimal bonding and part quality.
