## A fish strikes in an instant. Every axis carries the load.

The frame, spool, main gear, pinion, drag washers, bearing seats and level-wind mechanism form one continuous load and transmission chain.

The real CTQs are not isolated dimensions, but assembled coaxiality, center distance, gear mesh, drag stability and long-term corrosion resistance.

### 01 / RIGIDITY — Frame rigidity

Preserve the relationship between side plates, bearing bores and the spool axis under peak load

### 02 / SMOOTHNESS — Smooth drive

Bearing bores, center distance, tooth geometry and shaft fits define feel and noise

### 03 / DRAG — Stable drag

Face quality, washer condition and spring preload shape a repeatable drag curve

### 04 / MARINE — Marine durability

Materials, finishes, sealing and dissimilar-metal pairing must work as one system

## From 30 to 60 class Scaling changes the entire tolerance chain

As spool diameter, frame span and handle torque change, bearing support, gear center distance, thin-wall distortion and assembly clearances all re-enter the tolerance chain. Each platform needs its own material, blank, datum and finishing strategy.

These are real dual-axis reel programs manufactured with Zhongde involvement, spanning compact, core mid-size and large-format platforms.

### 60 CLASS — Wide-span load structure

A larger spool and frame span place greater demands on opposing bearing support, frame rigidity and machining-distortion control.

Frame rigidity · Shaft support · Distortion control

### 50 CLASS — Core production platform

Balance strength, mass and operating feel while controlling gear center distance, side-cover fit and anodized appearance consistency.

Strength-to-weight · Drive fit · Finish consistency

### 30 CLASS — Compact tolerance chain

As internal space tightens, thin-wall distortion, axial clearance and control-component fits become increasingly interdependent.

Thin-wall control · Assembly clearance · Control fit

## From side covers to the drive train Every part serves an assembled relationship

A dual-axis reel cannot be evaluated as isolated parts. Side covers establish shaft support, the spool carries geometry into rotation, the gear-and-shaft set transmits torque, and the handle converts internal precision into operating feel.

The components shown are manufactured and assembled parts that demonstrate the relationships among structural support, rotating axes, torque transmission and operator controls.

- STRUCTURE
- ROTATION
- DRIVE
- CONTROL

### 01 / SUPPORT & CONTROL — Side covers and control assemblies

Both housings locate bearings or bushings, support adjustment mechanisms and define assembly interfaces. One side passing inspection does not establish the shaft line; the opposing locations must share a controlled datum strategy.

CTQs: bearing-seat position · perimeter fit · control travel · assembly datums

### 02 / SPOOL AXIS — Spool and spool-shaft assembly

Lightweight spool geometry, support at both ends and shaft-end fits jointly determine start-up inertia, runout and high-speed stability, directly affecting casting and retrieve behavior.

CTQs: coaxiality · radial/face runout · dynamic balance · shaft-end fit

### 03 / DRIVE TRAIN — Main gear, mating gear and shafts

Tooth geometry, center distance and bore-to-shaft fits convert handle input into stable transmission. Gear parts must be evaluated together with side-cover bearing locations, housing datums and assembly preload.

CTQs: tooth mesh · center distance · bore/shaft fit · face condition

### 04 / HUMAN INPUT — Handle arm and grip assembly

Handle length amplifies input torque, while the mounting hole, grip shaft and rotational clearance define strength, backlash and feel. Exposed surfaces must also retain durability in marine use.

CTQs: hole position and profile · torque strength · rotational clearance · finish durability

### Machinable precision parts for fishing reels

Machinable parts are classified by functional system and connected to their primary CTQs so manufacturing requirements can be evaluated in the context of assembly relationships.

| System | Machinable parts | Primary CTQs |
| --- | --- | --- |
| Load-bearing structure | Main frame, left/right side plates, side covers, crossbars | Parallelism, bearing-bore position, assembly datums, structural deformation |
| Spool axis system | Spool, spool shaft, bearing seats, bushings | Coaxiality, radial runout, face runout, axial clearance |
| Drive system | Main gear, pinion gear, drive shaft, gear seats | Center distance, tooth mesh, bore/shaft fit, transmission noise |
| Drag & clutch | Drag seat, star drag, clutch lever, pressure plates | Flatness, friction-face condition, travel and repeatability |
| Control parts | Handle arms, knobs, adjustment knobs, end caps | Strength, profile, connection holes, operating feel |
| Level-wind mechanism | Worm shaft, line guide, slider and related components | Straightness, pitch, running resistance, travel fit |

### EXTENDED COMPONENT SCOPE

- Crossbars
- Bearing seats
- Drag pressure plates
- Clutch parts
- Level-wind parts

## Different parts need different process routes

Materials and process routes are matched to part function, production volume, loading and appearance requirements, with die casting, forging, CNC machining and finishing evaluated as one continuous manufacturing plan.

### ROUTE DECISION FACTORS

- Volume & tooling
- Structural load
- Weight & inertia
- Appearance grade
- Marine durability

| Part | Typical material direction | Typical process route | Selection logic |
| --- | --- | --- | --- |
| Body, frame, side cover | Die-cast aluminum, 6061 / 7075 aluminum | Die casting / forging / plate → CNC finishing → Surface treatment | Select by volume, structural strength, appearance grade and tooling investment. |
| Spool | Aluminum alloy | Turning → Milling → Deburring → Dynamic balancing → Anodizing | Prioritize low mass, runout and shaft-system stability. |
| Handle arm | Aluminum alloy or stainless steel | Forging / plate → CNC profile & holes → Polishing → Surface treatment | Select by handle length, applied load and appearance requirements. |
| Gears & shafts | Brass, stainless steel, alloy steel | Turning / gear cutting → Heat treatment → Finishing & inspection | Balance wear resistance, strength and transmission smoothness. |
| Grips & adjustment knobs | Aluminum, POM, engineering plastics, EVA | CNC or injection molding → Surface treatment → Assembly | Select by grip feel, weight, weather resistance and cost. |
| Appearance parts | Aluminum alloy, plastics | Grinding / polishing → Anodizing / coating / printing | Control color, gloss, tactile feel and durability in marine environments. |

A production route combines material, blank process, machining datums, finishing and inspection requirements, all aligned during quotation and DFM review.
