At Texlon Plastics, we understand that precision, reliability, and efficiency are critical in the world of plastic injection molding. A high-quality mold is the heart of any production line, and even the smallest defect can lead to wasted materials, downtime, and costly production delays. That’s why our plastic injection mold repair services are designed to restore your molds to peak performance, extending their lifespan and ensuring your operations run smoothly.

Comprehensive Mold Inspection and Assessment

The first step in any effective mold repair process is a thorough inspection. At Texlon Plastics, we start by carefully examining each mold for signs of wear, damage, or corrosion. Our team inspects cavities, cores, and critical components for cracks, pitting, scratches, and burn marks that can compromise part quality. Dimensional checks using precision tools such as micrometers, calipers, and coordinate measuring machines (CMMs) ensure that every cavity and core meets the exacting standards required for consistent production.

By identifying potential problems early, we can prevent minor issues from escalating into major failures that can halt your production line. Our detailed assessment allows us to create a targeted repair plan tailored to each mold’s condition and your production needs.

Cleaning: Preparing the Mold for Repair

Before any repair work begins, a mold must be meticulously cleaned. Residue buildup, grease, and rust can obscure defects and interfere with repair processes. Texlon Plastics uses a combination of chemical cleaning solutions and ultrasonic cleaning techniques to remove contaminants thoroughly. For more stubborn deposits or surface oxidation, our technicians employ mechanical cleaning methods such as abrasive blasting or wire brushing.

This cleaning stage not only exposes the mold’s true condition but also ensures that repairs adhere properly and deliver long-lasting results.

Minor Repairs: Polishing, Welding, and Filling

Not all mold damage requires extensive machining. Many issues can be addressed through minor repair techniques that restore functionality without altering the mold’s structure. At Texlon Plastics, our team specializes in high-precision polishing to smooth scratches, burrs, or corrosion marks on cavity and core surfaces. Polishing improves part quality and helps prevent defects like flashing or sink marks during production.

For cracks, broken edges, or other localized damage, we employ welding or brazing techniques, including TIG welding, laser welding, and bronze brazing, depending on the mold material. These methods restore structural integrity while maintaining the mold’s dimensional accuracy. Additionally, low spots or pits in the mold can be filled with specialized repair materials, such as nickel or beryllium-copper plating, to restore surface smoothness and ensure consistent part quality.

Precision Machining and Surface Restoration

Some mold repairs require more extensive machining to restore the mold to its original specifications. Texlon Plastics offers precision milling, grinding, and electrical discharge machining (EDM) to remove damaged sections and reestablish correct geometry. Our technicians can re-drill or re-tap broken ejector pin holes, repair venting channels, and reprofile cavity and core surfaces to exact design specifications.

This machining process ensures that each mold operates flawlessly, producing parts with consistent dimensions and high-quality surface finishes. By combining precision tools with skilled craftsmanship, we deliver repairs that meet even the most demanding industrial standards.

Hardening and Surface Treatments for Longevity

After repairs are completed, certain molds may require heat treatment or surface coating to restore hardness and durability. Welding or machining can alter a mold’s material properties, and re-hardening or tempering ensures that the repaired areas maintain optimal strength. Texlon Plastics also provides advanced surface treatments, including nickel and chrome plating, to enhance corrosion resistance and surface longevity.

These treatments not only protect your molds from future wear and tear but also contribute to smoother part ejection, reduced cycle times, and improved overall production efficiency.

Reassembly, Testing, and Quality Assurance

Once repairs and treatments are complete, each mold undergoes careful reassembly. Our team verifies that all components, including cavities, cores, slides, and ejectors, fit precisely and operate smoothly. Texlon Plastics then conducts trial runs on an injection molding machine to produce test parts, checking for dimensional accuracy, surface finish, and overall performance.

If minor adjustments are needed, we make them immediately to ensure that the mold performs flawlessly under production conditions. Every mold repair at Texlon Plastics is backed by rigorous quality assurance, giving our clients confidence that their equipment is restored to optimal performance.

Preventive Maintenance for Extended Mold Life

At Texlon Plastics, we believe that proactive maintenance is key to minimizing production interruptions. Our services go beyond repair to include preventive measures that keep molds in top condition. Regular lubrication, cleaning of slides and ejectors, and periodic inspections help identify early signs of wear, preventing costly downtime and extending the life of your molds.
