Understanding the Barriers to Utilizing Injection Molded Parts

1. Lack of Awareness of Benefits

• Identify the Advantages: Many manufacturers are not fully aware of the numerous benefits that injection molded parts can bring, such as cost-effectiveness, high precision, and ability to mass-produce complex shapes.
• How to Address It: Conduct workshops or informational sessions to educate teams about the advantages. Consider engaging industry experts to share case studies.
• Applicable Scene: When onboarding new employees or introducing a new product line, ensure that education on injection molded parts is included in the training materials.

2. Misconceptions About Costs

• Recognizing the Total Cost of Ownership: Some businesses hesitate to consider injection molded parts due to an initial perception of high tooling costs. However, the long-term savings in mass production often outweigh these upfront costs.
• How to Address It: Develop a cost analysis model that includes production runs over time, highlighting how investing in injection molded parts can lead to significant savings.
• Applicable Scene: When performing budgeting for a new project, present the cost analysis alongside examples of past successful projects using injection molded components.

3. Complexity of Design Changes

• Understand Design Limitations: Companies may shy away from injection molding due to the belief that design changes are difficult or costly.
• How to Address It: Utilize design software that supports rapid prototyping to showcase the flexibility of changes in designs without excessive production halts.
• Applicable Scene: During the product development phase, integrate iterative design sessions and utilize 3D printing for initial prototypes before committing to injection molding.

4. Supply Chain Issues

• Overcoming Supply Chain Complexity: The perception of complex supply chains when sourcing injection molded parts can deter manufacturers from fully embracing this process.
• How to Address It: Collaborate with reliable suppliers and establish relationships that facilitate smoother operations and better understanding of lead times.
• Applicable Scene: In periods of supply chain disruption, leverage relationships to quickly pivot to trusted injection molding suppliers who can ensure timely delivery.

5. Lack of Technical Expertise

• Building In-House Knowledge: The absence of experienced personnel in injection molding technology can limit its adoption.
• How to Address It: Invest in training sessions or hire experienced professionals familiar with injection molding techniques.
• Applicable Scene: When establishing a new production facility, a clear plan for staffing and training on injection molding processes should be made a priority from the outset.
