Batch customization production and sales of marble sample racks for an exhibition hall involve a structured approach that includes design, production, marketing, and distribution. Below is a detailed guide to help you navigate through these stages:

### 1. Design and Prototyping

#### Concept and Design:
- **Idea Generation**: Develop unique and functional designs for the marble sample racks. Consider designs that allow easy viewing and handling of heavy marble samples.
- **Material Selection**: Choose durable materials that can support the weight of marble, such as metal, reinforced wood, or high-quality plastic.
- **Prototyping**: Create prototypes to test the designs for stability, ease of use, and aesthetic appeal. Use feedback to refine the designs.

#### Tools and Software:
- **CAD Software**: Utilize CAD software like AutoCAD or SolidWorks to create detailed designs and models.
- **3D Printing**: Use 3D printing for prototyping small-scale models before full-scale production.

### 2. Production Process

#### Setting Up Manufacturing:
- **Equipment**: Ensure access to the necessary manufacturing equipment, such as metal cutting and welding machines, woodworking tools, and plastic molding machines.
- **Templates and Molds**: Create templates and molds for consistent production. These will help maintain the quality and uniformity of the racks.
- **Production Line**: Establish a production line that includes cutting, assembling, welding, painting, and finishing processes.

#### Quality Control:
- **Inspections**: Implement quality control checks at each stage of production to ensure the racks meet the required standards.
- **Load Testing**: Conduct load tests to ensure the racks can safely support the weight of the marble samples.

### 3. Customization Options

#### Customer Input:
- **Customization Portal**: Develop an online portal where customers can choose designs, sizes, colors, and finishes. Allow them to upload logos or branding elements for personalization.
- **Sample Approval**: Provide digital renderings or physical samples for customer approval before moving to bulk production.

#### Batch Production:
- **Small Batches**: Start with small batches to manage production costs and inventory efficiently.
- **Scalable Production**: Ensure the production process is scalable to handle larger orders as demand increases.

### 4. Marketing and Sales

#### Target Market:
