Insert Molding Process For Small Batch Of Table Connectors Production

This is a small batch production project we received in 2019. The project mainly completes table connector production for customers on a regular basis through rapid tooling.

Understanding the Customer’s Needs

Our client approached us with specific requirements for their table connectors:

• Small Batch Production: The client needed a modest quantity of 300 pieces per quarter
• High Durability: Given the structural role of table connectors, the products needed to be robust and durable.
• Precision Fit: The connectors had to ensure a perfect fit to facilitate easy assembly and ensure stability.

Despite the small batch size, First Mold was committed to delivering exceptional quality and value, ensuring our client’s needs were fully met.

Challenges in Insert Molding for Table Connectors

Insert molding involves placing a pre-formed component (insert) into a mold and then injecting plastic around it to form a single solid part. This technique is ideal for creating strong, reliable table connectors but comes with its own set of challenges:

• Thick Sections Leading to Sink Marks: The table connectors had thick sections which increased the risk of shrinkage, leading to potential dimensional inaccuracies and weakened structural integrity.
• Maintaining Precision: Ensuring that each connector met the exact specifications required meticulous control over the molding process.
• Cost-Efficiency for Small Batches: Providing a cost-effective solution for small batch production without compromising on quality required innovative manufacturing approaches.

First Mold’s Solution

1. Advanced Mold Design: Our engineers designed molds that specifically addressed the sink mark issue. By incorporating optimized cooling channels and precise control over the molding parameters, we minimized the risk of shrinkage and ensured consistent quality across all connectors.
2. High-Quality Materials: We used high-grade plastic materials with low shrinkage properties. Additionally, the metal inserts were sourced to meet exacting standards, ensuring the final product’s durability and reliability.
3. Process Optimization: Through rigorous testing and process optimization, we established the ideal injection parameters. This included controlling the injection speed, pressure, and cooling time to achieve the best results.
4. Cost-Effective Small Batch Production: Despite the small order size, we leveraged our efficient manufacturing processes to offer competitive pricing. Our commitment to providing value meant that the client received high-quality connectors at an affordable price, even in smaller quantities.
5. Quality Assurance: Each batch of connectors underwent stringent quality checks to ensure they met the client’s specifications. Our comprehensive QA process included dimensional checks, structural integrity tests, and fit assessments.
