Key features of the moon clutch purse frame

The value of the moon clutch purse frame comes from its uniqueness and adaptability in shape, performance, and craftsmanship. These characteristics not only determine the visual presentation and user experience of the bag but also directly affect the manufacturer's production efficiency, cost control, and quality stability.

Size And Shape

The size and shape of the moon clutch purse frame are not simply aesthetic design, but the result of the synergy of "capacity requirements, usage scenarios, and visual proportions", and its core characteristics are reflected in the "accuracy of the curve" and "the boundness of the scene of size".

① Proportional adaptability of the curvature of the curve

The arc of the moon clutch purse frame is not a fixed template, but dynamically adjusts with the width of the opening to maintain the visual balance of the "moon feeling". This feature requires manufacturers to:

Small frames (4-6 inches) should use a gentle curvature (arc radius 20-25cm) to avoid too steep arcs and cramped due to small size;

For large-sized frames (7-9 inches), the curvature (arc radius 15-18cm) should be appropriately increased to prevent the arc from being too flat due to excessive width and losing the recognition of the moon shape.

In mass production, the curvature deviation needs to be controlled at ≤1°, and the arc ratio of each batch is consistent through CNC molding equipment to avoid modeling deviations such as "flat moon" and "sharp moon".

② Strong correlation between size and capacity

The width of the moon clutch purse frame opening directly determines the capacity of the bag, forming a fixed adaptation relationship of "size - scene", which provides a clear basis for the manufacturer's product positioning:

4-6 inch frame: corresponding to mini capacity (0.3-0.8L), only suitable for "light carrying" scenarios such as dinner parties and parties, and needs to be matched with lightweight materials (such as thin diameter metal, thin composite materials) to avoid bloated shape;

7-9 inch moon clutch purse frame: corresponding to regular capacity (1-2L), suitable for the day

Buckle Mechanism:

The buckle mechanism is the most frequently interacted part of the moon clutch purse frame with users, and its core feature is the dual guarantee of "operation fluency" and "closure safety", which directly affects user reputation, and manufacturers need to optimize the process around these two characteristics.

① Smoothness and durability of operation

The "smoothness" of different fastening types varies significantly, and the durability needs to be verified through long-term testing, which determines the process accuracy requirements:

Ball socket buckle: Characterized by "silent and smooth", it is necessary to control the mating gap between the ball and the nest (0.1-0.2mm) to ensure that there is no lag in opening and closing, and at the same time pass 5000 cycle tests to avoid loosening after long-term use;

Kiss lock: characterized by "tight closure", the bite depth of the two "kiss-shaped" metal pieces needs to be ≥3mm to prevent items from falling, but the edges need to be chamfered (R≥0.5mm) to avoid scratching fingers;

Hook buckle: Characterized by "simple and easy to operate", suitable for lightweight bags, but need to add a non-slip bulge at the end of the hook to ensure a fit tolerance of ≤0.3mm to prevent accidental falling.

② Precise positioning of installation

The connection between the fastening parts and the moon clutch purse frame needs to be "accurately aligned", which requires the manufacturer to adopt a high-precision installation process: laser marking presets the mounting hole position, and the hole position deviation is ≤0.1mm to avoid the offset of the fastening part and the inability to close;

Preferential selection of welding (steel/brass) or die-casting integrated molding (zinc alloy) is preferred to replace screw fixation to reduce the risk of loosening in long-term use and ensure the fastening machine

Bending Forming Technology

The core manufacturing process of moon clutch purse frame is precise bending forming.

For metal materials, two main methods are used: hot bending and cold bending. Thermal bending is suitable for thicker or harder materials, and its plasticity is improved by local heating below the recrystallization temperature of the material, making it easier to form. This process requires precise control of heating temperature and time to avoid strength loss due to material grain coarseness.

Cold bending is suitable for materials with good ductility, and the pressure is applied to the mold, which can achieve better dimensional accuracy and surface quality.

The control of the bending radius is one of the process difficulties. Moon clutch purse frames often contain radii of curvature of varying sizes, with large radius regions requiring good ductility of the material and small curvature regions prone to stress concentrations. Manufacturers need to predict stress distributions through finite element analysis and improve safety factors by adopting gradient designs or increasing material thickness at critical areas.

As the core structural component and visual focus of the product, the moon clutch purse frame is designed and manufactured in multiple technical fields such as material science, mechanical engineering, and surface engineering. Manufacturers need to find the best balance between structural strength, aesthetic design, comfort of use, and cost control. With the development of new material technology and the diversification of consumer demand, the design and manufacturing of moon-shaped frames will develop in a more environmentally friendly, intelligent and personalized direction. A deep understanding of the technical points and quality control methods of the framework, as well as continuous optimization of production processes and supply chain management, is key for bag manufacturers to enhance product competitiveness and meet market demand.
