Precision Laser Welding
Laser welding is an increasingly popular alternative for mold repairs. Laser welding at Mold-Tech is an additive process using a Nd:YAG Laser and filler rods, as small as .003". With In-house laser welding, our experienced laser technicians can create precise welds with minimal downtime for our customers.
This process is useful when completing modifications, revisions and repairs including: texture repair, refurbishments, surface cracks, dinged edges and corners, damaged gates, nicked parting lines, galled thread cores, insert damage due to improper mold closing, end of arm tool damage, and damage caused by stuck parts/improper tool maintenance.
Advantages of laser welding:
- Quick turnaround keeps tool downtime to a minimum
- Precise control of the weld location
- Smaller weld amounts result in very little machining needed to restore steel to its original form
- Minimal discoloration of the surrounding material
- Retention of metallurgical characteristics
- Low heat reduces stress and sink
Materials that can be laser welded include:
- Hardened steels such as S-7, H-13, P-20, D-2, CPM, M-2 and Caldie
- Stainless steels: 440C, 420, 312 ,308, 316,17-4ph
- Copper alloys: Ampco, mold max, mold star, copper beryllium
- G2 Titanium
We understand production delays due to the loss in injection mold productivity. When a mold is not properly set up, closes on an improperly ejected part, or is degraded by wear, we know we need to get you back into production fast.
The injection molds repaired by Mold-Tech range from small to medium size. Experienced mold builders quickly assess the repairs necessary to bring an injection mold back into service.
Being able to design, build and repair tight-tolerance molds has been a key to the success of Mold-Tech. Each mold is built directly from the database that is used for the mold design, to ensure consistency from cavity to cavity and mold to mold.
Types of Molds Include:
- Prototype Molds
- Development Molds
- Bridge Molds
- Multi-Cavity Production Molds
- Hot Runner Molds
- Auto Unscrewing Molds
- Insert Molds
- In-Mold Decorating Molds (IMD)
- Micro Molds
- Metal Injection Molds (MIM)
- Liquid Silicone Rubber Molds (LSR)
- Shuttle Molds
- Multi-Shot Molds
- Stack Molds
Laser marking is used to serialize and create markings and engravings.
Alphanumeric characters, graphics, logos, bar codes, etc. can easily be applied to any flat and most curved surfaces. Laser marking technology has become increasingly precise and is useful for a wide range of applications and components.
Laser marking/engraving offers traceability for your molds and mold components. This fast, clean and efficient method allows for marking a wide range of materials inluduing stainless steel, tool steels, aluminum and titanium. Most commonly used for serialization and labeling for assembly, engraved mold components include: cavity blocks, core blocks, core pins, ejector pins, gibbs, inserts, locks, slides, slide inserts, and parting line identification.
