EDM Machining: Electrical Discharge Machining, Spark Machining / Eroding, Metal 3-D Geometry, Accurate Repeatability, Intricate Detail, Sharp Corners, Patterns

Electrical Discharge Machining (EDM) from SINCERE TECH provides CNC (computer numerical control) accuracy for creating 3-D geometry in hardened steel and other metals like brass, copper, and aluminum. It can be used to create simple or complex shapes. SINCERE TECH has 11 EDM machines, one AgieCharmilles EDM machine and one Sodick EDM machine for mirror surface EDM machining, two double heads EDM machines for high-efficiency EDM machining requirement

The EDM process is an excellent solution when a high degree of accuracy, and/or repeatability, is required.

EDM: What It Is and What It Does

Sometimes referred to as spark machining or spark eroding, EDM is a method of removing material by a series of electric discharges using copper electrodes or Graphite electrodes, rapidly arcing between an electrode acting as the cutting tool and the workpiece, in the presence of a dielectric fluid.EDM service

EDM is used to burn material away from the metal mold component, to add:

  • Intricate detail
  • Sharp corners
  • Patterns

The EDM cutting tool is computer-guided along the desired path very close to the work but does not come in physical contact with the piece, preventing plastic injection tooling marks.

A continuous sparking action produces a series of micro-craters on the workpiece and removes excess material by melting and vaporization. The particles are then washed away by a continuous stream of dielectric fluid.

EDM Services: SINCERE TECH Provides Quality Results and fast service for your plastic injection mold

SINCERE TECH’s EDM services can give your design potential a boost. You will be able to place intricate designs and logos in a wide variety of components with top quality results. This process can be used to produce:

  • Faceplates
  • Nameplates
  • Bezels
  • Buttons
  • Switches
  • Gears
  • And much more!

EDM can also be used in fabrication, for tapping holes into parts, and similar procedures.

If you are looking for a plastic mold supplier that offer you fast delivery, high gloss plastic molding parts, texture surface plastic mold, and all other custom plastic injection tooling or molded parts, you are welcome to send us your requirement, we will offer you the best price and quality.

Why American Plastic Mold Making Company Needs Apprentices

Over the course of the past 15 or so years, there is some mold making apprentices working in plastic mold maker shop. And these apprentices were all hired somewhat recently by the same plastic mold company.

What this means is that the guys with the specialized skills are getting ready to retire and there is nobody to replace them.  I’ve seen politicians give lip-service to enabling American manufacturing with tax incentives and programs, but, here in the shop nothing has changed. Nothing that I can see.

The only reason for these apprentices is that the CEO recognizes the need, not because anybody sent him information from a high-level seminar or meeting. The old guys made enough of a ruckus that the management actually responded.

Here are a few examples of what an apprentice will not be able to do for quite a few years:

  1. Fit delicate inserts. This requires an understanding of the function and fit of the mold component and a trained eye to tell the hand where to remove tiny amounts of hardened steel with files, stones, rotary tools, carbide burrs, sandpaper, diamond compound, grinding wheels, and so on.
  2. Surface grind mold components to .0002 inaccuracy. Never mind .0001 in.
  3. Assemble complex molds with hot runner systems, slides, lifters, hydraulics, micro-switches, etc.
  4. Troubleshoot problem molds.
  5. Operate any of the CNC machines when thinking outside the box is demanded, which is rather often.
  6. Make a mold component out of scrap, hardened tool steel in an emergency. This bypasses almost all the sophisticated machining and requires old-school know-how that takes a long time to learn.
  7. Grind finished core pins on a Ded-Tru centerless grinder to .0002 inaccuracy.

The list could go on and on, and the only people who have any idea what all this is plastic mold maker, who tend not to be all that communicative, generally.

So, unless companies are able to take on apprentices, work with local schools and do whatever it takes to get them trained quickly, we are in for a big bump in the road.

Today I believe very less people that work in the molds in American, there are looking for injection mold china partner to support them, this outsourcing is working very well to all of American, Europe and all of the companies on the world.

What Is high volume Injection Molding?

High volume injection moldingSINCERE TECH Plastic Injection Molding For Precision and Durability

High volume injection molding is the process by which industrial grade and ready to integrate plastic products are manufactured with sophisticated and advanced machinery. The very basis of production injection molding is using an injection mechanism to inject the raw plastic into a mold that shapes the molten plastic. This mold is then open with the help of a clamp that ejects the plastic parts. At SINCERE TECH, we are designing process with a scientific approach to reduce cycle time, reduce production cost and make a consistent product

Where Do They Use The Production Injection Molding Process?

This process is used across a number of industries and applications. Wherever they use plastics parts as an integral part of any product, they use the production injection molding process. This process was mainly conceived at the beginning of the twentieth century to facilitate the mass production of plastic items.

Today, it is aided by automation and robotics where CAD completely 3D part design and mold design files are sent to the manufacturing plant, and the plastic molds are created directly from referencing the file. This has streamlined the process and made it more efficient, both quantitatively and qualitatively.plastic molds
