Precision stamped components are integral to various industries, and molds play a crucial role in their production. When issues arise during the molding process, it’s imperative to swiftly identify the root causes and propose effective solutions. Addressing these problems skillfully not only prevents major failures but also reduces production costs and ensures a seamless manufacturing process. In this article, we will delve into one common challenge faced in precision stamping – mold jamming – and provide insights into its causes and remedies.

Common Causes of Mold Jamming

Mold jamming can disrupt the precision stamping process, and several factors can contribute to this issue. Here are some common causes and their respective solutions:

1. Improper Adjustment of Feeding Machine Parameters

Cause: Incorrect settings for feeding distance, material pressing, and relaxation.

Solution: Reevaluate and adjust these parameters to match the requirements of your precision stamping process.

2. Variations in Feeding Distance

Cause: Inconsistent feeding distance during production.

Solution: Regularly realign the feeding machine to maintain a consistent feeding distance.

3. Mold Aberrations

Cause: Mold stamping problems, possibly caused by bent cutters.

Solution: Rectify the issue by addressing the cutter’s bend and ensuring proper mold alignment.

4. Inadequate Guide Hole Diameter

Cause: The upper mold material pulls due to insufficient guide hole diameter.

Solution: Improve the guide holes in the convex and concave dies to ensure proper alignment and prevent material pulling.

5. Incorrectly Configured Stripping Function

Cause: Material carryover due to the incorrect configuration of the stripping function on the guide plate.

Solution: Adjust and amend the guide plate settings to prevent material carryover.

6. Uneven Material Stripping

Cause: Uneven stripping of material at bending or cutting positions.

Solution: Adjust the stripping spring’s force and consider other measures to ensure consistent material stripping.

7. Material Quality Issues

Cause: Material exhibiting a curved shape, excessive width, or substantial burrs.

Solution: Maintain control over material quality and, if necessary, substitute the material with higher-quality alternatives.

8. Thin Material Warping

Cause: Thin materials are prone to warping during feeding.

Solution: Install upper and lower material-pressing devices, as well as upper and lower material-extrusion safety switches between the feeding machine and the mold to prevent warping.

9. Mold Frame Alignment

Cause: Inadequate alignment of the mold frame, leading to significant vertical deviation from the feeding machine.

Solution: Reinstall the mold frame and ensure proper alignment to resolve the issue.

In the realm of precision stamping, molds play a pivotal role in determining the final product’s quality. Therefore, addressing mold defects with precision and timeliness is critical to maintaining a smooth and efficient manufacturing process. By understanding and mitigating the causes of mold jamming, you can ensure consistent and high-quality precision stamped components.
