Bakelite sheet is a phenolic laminated paperboard, which is made by hot pressing bleached wood pulp paper after being impregnated with phenolic resin. Its thickness ranges from 3 to 50 mm, and its regular sizes are 1030×2030, 1040×2080, 1220×2440. Common colors are reddish orange or black. Bakelite sheet is non-absorbent, non-conductive, high temperature resistant, and high in strength. It is widely used in electrical products and industrial fields.
Insulation: Bakelite sheet has excellent electrical insulation performance, good electrical performance at room temperature, and is suitable for insulating structural parts in electrical equipment.
High temperature resistance: Bakelite sheet can withstand high temperatures and is suitable for use in high temperature environments.
Wear resistance: Bakelite sheet has wear resistance and is suitable for use in mechanical molds and jigs on production lines and other occasions that require high wear resistance.
High mechanical strength: Bakelite sheet has good mechanical strength and is suitable for use in motors and electrical equipment with high mechanical performance requirements.
Electrical equipment: Bakelite sheet is often used in insulating switches, variable resistors and other components in electrical equipment.
Mechanical mold: Due to its high mechanical strength and wear resistance, bakelite sheet is widely used in mechanical molds, jig plates, mold splints, etc.
PCB industry: Bakelite sheet is suitable for drilling pads, distribution boxes, etc. in the PCB industry.
1. Clear requirements and specifications
First, clarify what kind of electronic or electrical equipment the bakelite sheet will be used in. Secondly, according to product requirements, determine the specific specifications of the bakelite sheet such as size, thickness, heat resistance grade, insulation performance, mechanical strength, etc.
2. Investigate the manufacturer’s qualifications and certifications
Understand whether the manufacturer has passed ISO9001 and other quality management system certifications, and whether it follows electronic assembly industry standards such as IPC. These certifications and standards are important proof of the manufacturer’s quality control capabilities.
3. Evaluate the manufacturer’s production capacity
Understand the manufacturer’s production scale, including the number of production lines, annual output, etc., to ensure that the manufacturer can meet your order needs.
Investigate whether the manufacturer’s production equipment is advanced and complete. Advanced production equipment is the basis for ensuring product quality and production efficiency.
4. Investigate the manufacturer’s quality control system
Understand the manufacturer’s inspection standards and processes for raw materials to ensure that the quality of raw materials meets production requirements.
Investigate whether the manufacturer has strict quality control measures during the production process, such as online testing, random inspections, etc., to ensure the stability of product quality.
Understand the manufacturer’s inspection standards and processes for finished products, including appearance inspections, performance tests, etc., to ensure that the products shipped meet quality standards.
5. Price and after-sales service
Price is an important consideration when choosing a manufacturer. Choosing a manufacturer that provides factory direct sales services can ensure that the price is reasonable and transparent. At the same time, good after-sales service, such as spot delivery and quick response to customer needs, is also an important aspect of evaluating the quality of the manufacturer’s service.
6. Refer to customer reviews and cases
Refer to other customers’ reviews and feedback to understand the manufacturer’s actual cooperation experience and project success rate. Market reputation is also an important reference for evaluating the quality and reputation of the manufacturer.
7. On-site inspection
If conditions permit, it is recommended to conduct an on-site inspection of the manufacturer to intuitively understand the manufacturer’s production environment, equipment, process, etc.
