Why Mold Trial (T1) Is a Crucial Step in Injection Mold Validation

Before mass production begins, every injection mold must pass a critical phase: the T1 trial—also known as the first mold test. At Dongxinda Mould Technology Co., Ltd., we treat T1 as a structured, data-driven process to ensure your mold delivers the expected part quality, cycle time, and reliability.

What Is the Purpose of T1 Trial?

• Validate mold structure and component movement (sliders, lifters, ejection)

• Confirm part dimensions, surface finish, and tolerance

• Check for defects like warpage, short shots, sink marks, or flashing

• Optimize process parameters: pressure, temperature, cooling, and cycle time

Our Standard T1 Trial Procedure Includes:

• Running client-specified resin or equivalent

• Recording molding parameters and material behavior

• Measuring parts using precision instruments (CMM, calipers, projectors)

• Issuing a T1 trial report with part photos and dimensional inspection

• Providing mold and part improvement suggestions if needed

This step ensures that clients receive not just a mold, but a proven production-ready tool.

FAQs:

• Can clients attend the T1 trial in person or online?
  Yes. We offer both on-site and video/live-streamed trial sessions.

• How many samples are provided?
  Typically 5–10 pcs, including dimensionally measured parts.

• What if parts don’t meet tolerance?
  We analyze root cause and modify the mold before T2, free of charge.
