1、 Understand the basic composition of a biaxially oriented mesh production line

Biaxial Oriented Net production line is a professional equipment used for producing plastic mesh materials, widely used in agriculture, construction, packaging and other fields. A complete two-way stretch mesh production line typically consists of the following main components:

Extrusion system: including extruder, die head, etc., responsible for melting and extruding raw materials

Longitudinal stretching system: achieving longitudinal stretching of materials through rollers of different speeds

Lateral stretching system: usually using a stretching machine structure to achieve lateral stretching of materials

Standardized cooling system: stabilizing product size and performance

Roll up system: Roll up finished products into rolls

Control system: PLC or computer control system, monitoring the entire production process

2、 Clarify one's own needs

Before selecting equipment, it is necessary to clarify one's own production needs, which is the basis for choosing the most cost-effective equipment:

Product specifications: Clearly define the parameters such as mesh size, width, and thickness range to be produced

Raw material type: Determine whether PP, PE or other special materials are mainly used

Production requirement: Determine daily/monthly/annual production demand based on market forecast

Site conditions: Evaluate the infrastructure conditions such as factory space and power supply

Budget range: Set a reasonable equipment investment budget

3、 Key considerations for equipment selection

1. Equipment performance and quality

Extruder configuration: screw diameter, aspect ratio, motor power and other parameters should match production needs

Precision of stretching system: The adjustment range and precision of stretching ratio directly affect product quality

Temperature control system: stability and accuracy of temperature control in each section

Automation level: High automation equipment can reduce labor costs and improve consistency

2. Manufacturer selection

Manufacturer qualification: Priority should be given to professional equipment manufacturers with industry experience

Technical Strength: Assessing the manufacturer's research and development capabilities and patented technology

After sales service: A comprehensive after-sales service system is crucial

Market reputation: refer to the evaluation and user experience of users in the same industry

3. Cost effectiveness evaluation

Initial investment cost: including equipment price, transportation and installation costs, etc

Operating costs: Long term operating costs such as energy consumption, labor, maintenance, etc

Production efficiency: Unit time output and product qualification rate

Equipment lifespan: expected useful life and depreciation period

4、 Purchasing strategies and techniques

1. New equipment vs used equipment

New equipment advantages: excellent technology, complete warranty, stable performance

Advantages of second-hand equipment: low price, fast investment recovery

Risk Warning: Second hand equipment may have hidden faults and require professional evaluation

2. Domestic vs. imported equipment

Domestic equipment: obvious price advantage (usually 1/3-1/2 of imported equipment), fast after-sales service response

Imported equipment: leading technology, high stability, but expensive price and long supply cycle of accessories

Compromise solution: Consider importing key components and assembling semi domestically produced equipment domestically

3. Customized solutions

Standard equipment may not fully meet special needs

Communicate with manufacturers to customize solutions, balance special needs and costs

Pay attention to the compatibility and future upgrade space of customized devices

5、 Cost Control and Investment Return Analysis

Calculation of equipment investment payback period: Calculate the payback period based on expected production and profit

Energy consumption optimization: choose energy-saving equipment to reduce long-term operating costs

Maintenance cost estimation: Understanding the price and replacement frequency of vulnerable parts

Capacity reservation: Consider future expansion needs appropriately and avoid repeated investments in the short term

6、 On site inspection and machine testing

Visiting the manufacturer's production base: understanding the actual production environment and process level

Investigating user cases: on-site inspection of the operation of similar equipment

Trial machine verification: Conduct raw material trial production under conditions

Performance testing: Verify whether the nominal parameters of the device are consistent with its actual performance

7、 Notes on Contract Signing

Technical Agreement: Clarify equipment technical parameters and acceptance standards

Payment method: Reasonably arrange payment progress and reduce risks

Delivery time: Clearly define the delivery time and delay compensation terms

Training terms: Ensure that operation and maintenance training is in place

Warranty terms: Clearly define the scope and duration of the warranty

When selecting equipment for a two-way stretch mesh production line, multiple factors such as technical performance, price, and after-sales service should be comprehensively considered to avoid blindly pursuing low prices or choosing high-end equipment. Suggest adopting the following strategies:

Choose appropriate configurations based on actual needs, and do not blindly pursue high-end configurations

Priority should be given to well-known domestic brands with excellent after-sales service

Properly reserve upgrade space to adapt to future development

Pay attention to the energy consumption indicators of equipment and reduce long-term operating costs

Establish a comprehensive equipment file for easy maintenance and management in the future

Through scientific evaluation and rational selection, a more cost-effective solution for the production line of biaxially stretched mesh can be found, creating maximum value for the enterprise.
