I. Product Overview

This long rod connector is integrally formed by metal thin plate through multiple stamping and bending processes, featuring a slender rod body with multi-angle bent ends. The rod body is designed with a long adjustable waist hole at the top and a positioning circular hole in the middle. The waist hole structure allows for micro-adjustment of the installation position, precisely controlling the push-pull travel of the mechanism. The bent hinge structure at the end is compatible with shaft assembly, converting straight-line thrust into oscillating force to complete internal linkage control of equipment switches, valves, and temperature control components. The metal plate has excellent toughness, can buffer vibrations during operation, and the nickel-plated surface effectively prevents rust and oxidation, making it resistant to rust and deformation over long-term use.

Stainless steel, manganese steel, carbon steel, and other raw materials can be selected as required. The lengths of rods, bending shapes, and hole arrangement can all be precisely replicated according to customer drawings or physical samples. New products undergo small batch trial runs and adjustments. Once qualified, large-scale stable supply is ensured. Bending accuracy and elastic force are inspected and calibrated item by item before shipment.

Chapter Two: Core Highlights of Craftsmanship

1. Steel strip integrated stamping, bending and forming, not easy to deform and rebound
   The entire rod is seamless welded without joints, the bending position is treated with stress annealing, and the repeated pull and push swinging angle will not deviate, ensuring long-term stable transmission accuracy.
2. Combination design of waist hole and round hole, stroke freely adjustable
   The central circular hole serves as a pivot point, the upper elongated hole is used for fine-tuning the initial stroke, one connecting rod can accommodate multiple assembly requirements, enhancing its versatility.
3. End-folding hinge joint, smooth swing without jamming
   The double-bend clip structure is compatible with pivot pin hinge, with moderate gaps, allowing smooth reciprocating pull-push movement without jamming or unusual sounds.
4. All-around burr removal + overall electroplating, safe and durable assembly
   The edges of the board cutting and the inner walls of the holes are all deburred and polished, combined with a uniform electroplating layer, which neither scratches the matching plastic or metal parts nor prevents rust by isolating moisture.

Section 3: Optional Customizable Raw Materials

1. 304 Stainless Steel (Recommended)
   Anti-rust toughness balanced, suitable for both dry and wet environments, the first choice for transmission rods in small appliances and precision instruments.
2. 65Mn manganese steel
   Higher resilience hardness, suitable for high-frequency reciprocating swing conditions, fatigue-resistant and not easy to bend or break.
3. 201 Stainless Steel
   Outstanding cost-performance, conventionallinkage structure for indoor drying equipment selection.
4. Phosphor bronze
   Electrical interlock components with both conductivity and elasticity, requiring grounding and conduction.

4. Optional Surface Treatment Processes

• Bright Nickel Plating (Actual Shooting Process): Appearance glossy, anti-oxidation and rust-proof, the first choice for general electronic and household accessories.
• Electroplated zinc: Economical anti-rust solution for carbon steel substrates

Chapter 7: Frequently Asked Questions on Procurement Q&A

Q1: Can the rod length and bending angle be changed arbitrarily?
A: Yes, all external dimensions can be adjusted to fit the internal space of the equipment.
Q2: Which material is more durable for frequent back-and-forth movement?
A: Preferably use 65Mn manganese steel material, which has the best fatigue resistance, and it is not easy to deform after one million swings.
Q3: Can the number of bending sections be increased to form a multi-bend, irregular connecting rod?
Support: Any number of bending and non-standard profile linkages can be die-cast.
Q4: Can the sheet thickness be increased as required to enhance load-bearing capacity?
A: Sheet thickness can be customized from 0.2mm to 3.0mm, with greater thickness offering higher compressive and load-bearing capacity.
