  Reverse Engineering (产品开发) -
  Our company has more than 10 Professional Engineers that could help you design product from initial concept up to manufacturing into finished product. The standard software that we use are UG and PRO-E, although we can also use Solid works, catia, autocad, etc, depending on your availability. We have professional people in the field of designing, plastic manufacturing, metal hardware requirements, and electronic assembly.
  With this service that we offer, our client can just easily send us a sample or drawing or just an idea, then we can easily provide them a report that would suggest how the product will be made, the process involved, the engineering structure of the product, the estimate cost of the project and the lead time. This report will come with an engineering drawing that will show all the specifications, dimensions and suggested material.
  Prototyping (首板制造) -
  Sometimes, customers request prototypes to test assembly compatibility or to know what their product will look like when it is produced through injection molding so we provide prototypes of their products. We understand that it will usually cost a lot of investment in coming up a new product, so to lower down your risk, we provide prototyping service to our client. Prototyping is a way of making a finished product without building a tool by means of machining ( CNC ) to provide you with a sample of how your part will look, feel, and perform. The cost of making prototype samples are much less than building a tool.
  Plastic Tool and Mold Manufacturing (模具制造) -
  Our Mold Division is one of our biggest strength. Eighty percent (80%) of our Molds are exported to U.S., Brazil, Italy, Germany, France, Japan and Taiwan. We have complete manufacturing facilities from CNC, EDM, Wire Cutting, Milling, Drilling all located in one roof. Our Mold Flow Analysis program ensures that potential processing problems are highlighted at an early stage just before we start building our molds. All of these make our Mold Division a very professional, well-oriented, high precision mold making factory in China.
  Plastic Injection (注塑成型) -
  We specialize in plastic injection for a wide range of OEM service.  Our plastic injection machines vary in size from 90 tons to 450 tons. We specialize in tight tolerance parts requiring very precise quality control measures to general plastic parts that need to be molded at a very reasonable price. Flexibility is what helps us to grow and to deliver high quality parts time after time. From single custom-made parts to high cavitation or over-molding, we are always ready to cater to your production needs.
  Secondary Services (二次加工) -
  Our Secondary Services involves Spray Painting lines with 26 ( big ) spray cubicles. We also offer in-house services for silk and pad printing, hot-stamping, sonic-welding and assembly needs. With our company, our client can experience a one-stop OEM manufacturing service.

  • We do quotations fast and reply to inquiries promptly. Just send us engineering drawings then we can give our tool and product quotation within 3 days depending on the complexity of the product. We often win projects because of our dedicated service and swift & accurate quotation.
Other than Plastic Tool and Mold Manufacturing, Injection Molding, and other services listed in our Products & Services, Richfields also does the following in relation to Plastic Tool and Mold Manufacturing:
Making a product 3D model - When customers do not have readily available resources to make product 3D model, we can provide this service upon request so that customers have an idea of what their product looks like when viewed with 3D software.
Mold Flow Analysis - A mold flow software gives a lot of valuable information to the customer and to the injection molder such as: cycle time and possible filling problems. It simulates the injection molding process and the molder is able to improve the mold's designs based on results from the Mold Flow Analysis. Many possible problems are avoided early on.
Mold and Tool Designing - This is also applicable to customers who do not have the software to design the mold. We can design the mold for you and you can just confirm the mold design before we produce the tool.
Mold Trials - Having injection molding facilities, Richfields is able to produce molds effectively, no need to go to another shop to test our molds!
Inspection Reports on Articles Produced From Mold Trial - We test articles produced from the molds and compare the results with dimensions from the layouts confirmed by our customer.
Our Measuring Equipment Include - CMM from Mitutoyo, calipers, 2D projector, pin gauge, and height gauge. Other tests specific to specialized industries are also available upon request. We provide balloon print to customers together with the measurements for easier checking from the customer’s side.
