Plastic Injection Mold Repair

Some molds need localized repairs after an isolated incident, while others require extensive restoration after years of continuous use. Thogus’s specially trained tooling engineers plan each repair around the condition of the mold and the performance expectations of the customer. 

Repair projects often include: 

• Cavity and core restoration 
• Weld repair for damaged tooling 
• Ejector pin and ejector system repair 
• Slide and lifter repair 
• Leader pin and bushing replacement 
• Vent and cooling channel cleaning and repair 
• Surface polishing and texture restoration 
• Parting line and shutoff restoration 

Injection molds operate with extremely tight tolerances. Even minor wear can create flash, dimensional deviations, cosmetic flaws, or filling issues that halt operations. The longer a mold remains out of commission, the greater chance it has to significantly tarnish customer relationships and manufacturing output. Thogus’ proven plastic injection mold repair process is formulated to minimize delays without sacrificing accuracy.

Our technicians go beyond replacing parts. We provide exceptional plastic injection mold repairs using proven machining, fitting, polishing, and assembly techniques. Upon completion, every part of the mold is inspection to confirm that the tool is fully restored and ready to continue service.

Short-term solutions are not an option when injection molds are used to create critical components for healthcare, industrial, automotive, and consumer products. Thogus takes plastic injection mold repair seriously. That is why our technicians take the time to conduct detailed mold inspections and identify all signs of wear. This allows us to perform repairs that provide a true resolution. 

We communicate openly throughout the repair process, offering practical recommendations and clear explanations of the work required so customers know what to expect. Our goal is to avoid surprises when the mold returns to production. 

With our mold transfer services, sometimes a tool arrives at our facility in need of repair after years of use. Also, in many cases previous maintenance records are incomplete, making a detailed inspection an important first step. Our engineers evaluate the tool’s surfaces, moving components, cooling elements, and alignment features to identify issues that could hinder future performance.  

We then perform the necessary repairs so the mold can move to production in our facility. This detailed process gives us a clear understanding of the mold's condition, allowing future maintenance to follow a more predictable schedule.
