Custom Double Groove Slotted Disc Springs | SUNZO Factory

Premium custom double groove slotted disc springs manufactured by SUNZO. Offering customizable groove size and conical designs to meat precise load-deflection requirements.

In precision aerospace assemblies, high-pressure hydraulic actuators, and heavy-duty automotive transmissions, spatial restrictions often clash with high force demands. Mechanical engineers configuring these tight spaces require custom internal components that can deliver high load-bearing capacities with flexible, extended deflection ranges.

Standard single-piece elastic elements frequently exhibit a rigid, linear stiffness curve. When pushed past their normal boundaries, they often experience localized stress concentration, early micro-cracking, and rapid load relaxation. These defects lead to uneven load distribution, sudden calibration drift, and premature system breakdowns in complex automated equipment.

As an globally recognized high-tech manufacturing pioneer in precision industrial elasticity solutions, Jiangsu Sunzo Elastic Technology Co., Ltd. (SUNZO) specializes in manufacturing premium Custom Double Groove Slotted Disc Springs. Engineered with precise radial slots, our specialized components provide stable, extended deflection curves within narrow envelopes, offering a reliable choice for international tier-1 OEM procurement managers looking to optimize high-stress mechanisms.

To satisfy the strict technical standards of global machinery and precision system builders, Sunzo provides a comprehensive manufacturing framework centered around flexible elastic profiling:

The specific depth, width, and spacing of an internal spring's slots directly control its operational performance. Sunzo addresses this mechanical requirement by providing a full suite of Customizable Groove Size (可定制槽尺寸) design configurations. Our technical team works alongside your design group to optimize the slot profile, modifying the mechanical spring curve to achieve a softer, more progressive force delivery that standard conical designs cannot provide.

Standard slotting techniques can leave behind rough edge tears, microscopic micro-cracks, and dimensional variations that alter spring performance. Sunzo eliminates these issues by utilizing a dual-track manufacturing approach:

• High-Precision Wire EDM Processing: For complex prototypes or thick-gauge premium alloys, we utilize ultra-precise wire electrical discharge machining (EDM) to profile the slots with high accuracy. This process avoids introducing thermal stresses or micro-fissures along the cut lines.

• Automated Progressive Stamping: For high-volume production orders, our facilities utilize precision multi-stage progressive stamping dies to form identical Double Groove (双槽) structures with exact dimensional consistency across every production batch.

Our combination of advanced geometric layout and precise cutting allows our Slotted Disc Springs to handle demanding mechanical cycles:

• Uniform Stress and Force Distribution: The dual-groove layout on both the internal and external diameters spreads mechanical energy evenly across the component surface during compression, preventing concentrated stress peaks.

• Extended Deflection in Limited Spaces: The slotted configuration lowers overall spring stiffness while extending the total deflection range, allowing it to store high force within a compact physical layout.

• Stable, Long-Term Operation: This uniform distribution limits material fatigue and permanent height loss, helping keep system calibration steady over long operating lifecycles.

Sunzo utilizes premium alloy and stainless steel wire with full traceability, matching structural options with protective surface treatments to suit diverse industrial applications:

To ensure zero-defect consistency before shipping across international supply chains, Sunzo implements rigorous testing within our ISO 9001-certified testing facilities:

• 100% Dimensional Inspection: High-resolution digital optical comparators and laser sorting systems verify slot depth, inner diameter, outer diameter, and overall thickness to stay within strict tolerance windows.

• Load-Deflection Curve Mapping: Automated hydraulic compression testing tracks force-deflection profiles on every manufacturing batch to verify compliance with your specified design parameters.

• Microstructural Verification: Ultrasonic and magnetic particle inspections check raw material integrity to ensure all components are free of sub-surface defects or manufacturing flaws.

Jiangsu Sunzo Elastic Technology Co., Ltd. (SUNZO) operates a state-of-the-art production infrastructure designed to ensure absolute international supply chain security. Housing more than 200 large-scale punching systems, automated flat-wire coiling nodes, multi-axis CNC forming machinery, and atmosphere-controlled tempering furnaces, Sunzo comfortably scales production from rapid non-standard prototyping to high-volume multi-container global contract shipments.

Our production facilities operate under strict international management systems, holding active quality certifications for IATF 16949 (Automotive Quality Management) and ISO 9001 (Quality Management).

• Secure Seaworthy Packing Protocols: Product batches are packed using export-grade standards, including heavy-duty reinforced cartons or fumigated wooden boxes secured on solid wooden pallets to prevent oceanic humidity damage.

• Rapid Delivery Pipelines: Located close to major international shipping routes like Shanghai Port, Sunzo guarantees a highly competitive 10-day delivery lead time for standard inventory components.
