Progress and Flow of Work for Custom Hot Runner Components

At JC Machining, we take great care to ensure the accuracy and precision of our custom hot runner components from the very beginning of the process.

During the initial stages of planning and development, we pay close attention to all details, size, dimensions, and tolerances and ensure that 3D data is 100% accurate to avoid any potential issues during production.

We use 3D CAD data, technical drawings, and CNC machines and thoroughly check programming and machining before production begins. Our machinists pay high attention to detail to ensure that our components meet the exact specifications of our clients and provide the best performance for our customers.
