Richconn: Secondary Services

Many of our customers order parts that come ready-made from plastic injection molding or CNC machining. Many others, however, want or need "secondary machining" of the parts so produced. These processes are referred to as "secondary services." They can be an integral part of a customer's project requirements.

Why Secondary Services?

Secondary services may be required to meet the process control, functional, or cosmetic (usually branding or labeling) requirements of a given project. These requirements will determine if additional services are needed.

The customer may have very specific requirements for oversight of the design and development process (monitoring and recording part dimensions) such as additional sampling and detailed measurements.

Sometimes the parts are components of an assembly that must first be assembled and then incorporated into the final product. Automated sub-assembly and final assembly may not be economical for the customer for on demand manufacturing runs. By supplying fully assembled sub-assemblies, time and cost advantages can be realized through simpler final production.

Frequently Used Secondary Services

There is a wide range of secondary and support services that can be provided for injection molded and CNC parts. Common ones include:


# Detailed inspection and measurement (to support PPAP and other industry standard quality control processes).
# Anodizing  of aluminum CNC parts
# Structuring of customer mold
# Ultrasonic welding. Ultrasonic welding applies high frequency acoustic vibrations to join two components by friction. The process is particularly useful for joining dissimilar materials. It can also be used to add metal inserts to injection molded parts after molding.
# Hot caulking. In hot caulking, metal or threaded inserts are inserted into plastic parts after molding and positioned using heat and pressure.
# Pad printing. Pad printing involves filling a steel plate with an etched pattern with ink, which is then transferred to an injection-molded plastic part. This allows a part to be quickly and economically imprinted with a logo, part number, graphic instructions or other text or images.

# IML (In-Mold Labeling). In the IML process, a printed label is inserted into a mold before the liquid plastic is injected. When the mold is filled with the plastic, the label is firmly bonded to the part.
# Laser Etching and Part Marking. Laser etching uses a laser to etch a contrasting image or text into a plastic part.


Richconn's secondary services are now being gradually introduced, starting with:

* Inspection and measurement
* Mold structuring
* Anodizing serivice
* Simple assembly
