Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process where a thin single strand metal wire, along with de-ionised water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks, while preventing rust. Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode. Due to the inherent properties of the process, Wire EDM can easily machine complex parts and precision components out of hard conductive materials. To stop the sparking process from shorting out, a non-conductive fluid or dielectric is also used in the process. The waste material is removed by the dielectric, and the process continues. EDM parts from prototypes to full production with tight tolerance and complex construction.

We provide metal stamping services for a wide variety of industries, including aerospace, military, medical, construction, and automotive. Just a few of the applications in which our stampings are used are electric motors, air bags, appliances, sporting goods, microelectronics, and lighting fixtures. We can work to tolerances of ±0.001″, and meet ISO, AS, and Mil-Spec compliances. We are happy to accept orders from short runs of 10 or more, up to and including millions of units. Metal stamping is a complex process that can include a number of metal forming processes —blanking, punching, bending, and piercing and more. Blanking: This process is about cutting the rough outline or shape of the product. This stage is about minimizing and avoiding burrs, which can drive up the cost of your part and extend lead time. The step is where you determine hole diameter, geometry/taper, the spacing between edge-to-hole and insert the first piercing.

SLS 3D printing uses a high-powered laser to fuse powdered material together into a desired 3D shape. This professional-grade technology is ideal for both functional prototyping and small production runs, as it offers a high degree of design freedom, SLS 3D printing uses a high-powered laser to fuse powdered material together into a desired 3D shape. This professional-grade technology is ideal for both functional prototyping and small production runs, as it offers a high degree of design freedom, high accuracy, and exceptional mechanical properties. Although SLS 3D printing was previously restricted to bulky and expensive machines, recent advancements have led to the development of more affordable and compact SLS machine.There are now a handful of desktop SLS 3D printers on the market, and even industrial-sized machines have become relatively inexpensive compared to traditional digital fabrication techniques.

While delivering prototypes to customers, we were frequently asked if we could provide low-volume metal casting services. Because of this, we started to look for metal casting suppliers in order to fulfill those needs. While delivering prototypes to customers, we were frequently asked if we could provide low-volume metal casting services. Because of this, we started to look for metal casting suppliers in order to fulfill those needs. Unfortunately, the search proved frustrating. Big casting companies showed no interest in low-volume production, while the small casting companies couldn’t meet our quality requirements. It presented a challenge, but we took it as a business opportunity: if it was difficult for us to find the right companies for these projects, we knew it would be a good deal harder for overseas customers to find them. After two years, we successfully developed relationships with a handful of medium-size casting partners who can meet our quality requirements and lead time requests. We are now able to offer high-pressure die casting in aluminum, magnesium and zinc, as well as investment casting in brass and all types of steel. Why use Sun-Tech for Metal Casting? It might sound counter-intuitive to use a RP company for metal casting services, but we offer very good reasons for doing so: We have built up an excellent relationship with our partners for pressure die casting and investment casting. We have a huge amount of precision CNC machines for post-machining With our project management experience, we can guarantee a smooth transfer of information and punctual delivery.

Sun-Tech is fully capable of handling your vacuum casting and silicone molding needs. With years of expertise in the field, we can fabricate your parts to the highest standard and with fast turnarounds. Vacuum casting is a great way to make rigid or flexible parts, and is ideal for prototypes, engineering testing, concept proofing and display demos. These parts can be made from hundreds of casting polymers. Vacuum casting is a manufacturing technology that uses a vacuum to draw liquid material into a mold. It differs significantly from injection molding, which pushes liquid material into a mold using a screw. The process of vacuum casting offers significant advantages, and is particularly useful for parts that have undercuts or fine details. The process starts with a master model, which 3ERP creates using one of its CNC machining centers — though 3D printing can also be used. This master model is then immersed in liquid silicone, which is cured and becomes the mold. Advantages of Vacuum Casting 1 Fast turnaround Sun-Tech can provide up to 20 parts in 15 days or less, depending on part specification and volume. 2 Affordability Silicone molds are less expensive than the tooling used for injection molding, resulting in low prices. 3 Capable of producing large parts Depending on the type of equipment used, vacuum casting can to create very large parts. 4 Superior surface finish to injection molding The vacuum process removes air bubbles and allows the material to capture fine details. 5 Color options Coloring pigments can be added to the resin for a variety
