Plastic Injection Mould Repair
Expert repair welding for plastic injection moulds using laser, micro-plasma, and TIG welding processes. We restore damaged cutting edges, pockets, and worn surfaces to original tolerances while maintaining hardness and minimizing heat-affected zones.
Micro-welding services for small and delicate plastic components requiring controlled heat input and minimal distortion. Ideal for sensors, medical devices, thin sheets, and custom assemblies where conventional welding methods fail.
Specialized repair welding for pressure die-casting dies including HPDC and LPDC applications. Our multi-process approach ensures economical repairs with same-as-original hardness and extended tool life without additional heat treatment.
Advanced material deposition techniques to rebuild worn or damaged plastic working tools instead of replacement. We selectively add material to restore original geometry, preserving tool strength and enabling multiple life cycles.
Expert repair services for compression and thermoset moulds used in plastic manufacturing. Our controlled welding processes restore damaged areas while maintaining the precise tolerances required for consistent part production.
Mobile repair capabilities for moulds and dies that cannot be transported. Our technicians bring advanced welding equipment directly to your facility, minimizing downtime and maintaining production schedules.
Advanced Plastic Welding Technology Tailored to Your Industrial Needs
At Wintegral Engineering, we understand that every plastic mould, die, and component represents a significant investment in your manufacturing capability. Our job-shop facility is equipped with six different welding technologies—including laser welding, micro-plasma welding, micro-GT, TIG welding, and micro-cladding—allowing us to select the most economical and effective method for each unique repair challenge. We work with tools of any size, shape, or weight, from delicate 50-gram components to massive 20+ ton dies. Our proprietary hybrid welding techniques and use of world-class materials from renowned suppliers ensure repairs that match or exceed original tool performance, all while maintaining our industry-leading welding defect rate of less than 1%.

Frequently Asked Questions
What types of plastic welding processes do you offer?
We offer six different welding technologies: laser welding, micro-plasma welding, micro-GT welding, TIG welding, micro-cladding, and proprietary hybrid laser-micro GT welding. This multi-process capability allows us to select the most economical and effective method for each specific repair, whether it's a delicate medical component or a massive die-casting die.
Can you repair plastic moulds and dies of any size?
Yes, we repair moulds and dies of any size, shape, or weight—from delicate components weighing just 50 grams to massive tools exceeding 20 tons. Our facilities are equipped to handle plastic injection moulds, pressure die-casting dies, compression/thermoset moulds, rubber moulds, and metal injection moulds regardless of dimensional constraints.
How do repaired tools compare to new replacements?
Our repaired tools perform like new and often exceed original tool life. We restore cutting edges and damaged areas to original tolerances with the same hardness as the base metal, requiring no further heat treatment. Our certified concentricity and straightness guarantee negligible radial and axial runout, ensuring consistent performance.
What is your typical turnaround time for plastic welding repairs?
Turnaround times vary based on the complexity and extent of damage, but we prioritize timely deliveries to minimize production disruptions. After technical analysis, we provide a delivery timeline estimate with your quotation. For urgent or production-critical repairs, we offer expedited service to meet your schedule requirements.
Do you offer onsite plastic welding services?
Yes, we provide onsite repair services for moulds and dies that cannot be easily transported due to size, weight, or production constraints. Our technicians bring advanced welding equipment directly to your facility, enabling repairs without removing tools from your production environment.
What materials can you weld for plastic working tools?
We work with all common tool steels including H-13, H-21, H-11, P-20, S7, D2, M2, and SS420, as well as non-ferrous metals like titanium, beryllium copper, copper, and aluminum. We use the highest grade welding materials sourced from world-renowned suppliers to ensure metallurgical compatibility and long-term performance.
How much can I save by repairing instead of replacing?
Repair costs are significantly lower than new tool manufacturing, with dramatic savings that vary based on tool complexity and damage extent. Beyond direct cost savings, you also avoid long lead times associated with new tool procurement and the production downtime that comes with tool replacement.
What quality guarantees do you provide?
Every repaired tool comes with an exclusive certificate for concentricity and straightness. We maintain an industry-leading welding defect rate of less than 1%, and our repairs exhibit the same hardness as the base metal with minimal heat-affected zones and very little or no weld sink, ensuring reliable, long-lasting performance.
