Richfields Plastics provides cost efficient and high quality plastic injection tooling services. Providing Plastic Mold Design services is part of our commitment to fulfill our customer’s requirements through comprehensive plastic injection tooling and molding services. Our designers and engineers work closely together with customer to fully understand detailed customer requirements.
Richfields’ strict quality procedure ensures that molds produced by our team are machined and built only according to customer instructions. One key advantage of Richfields is that we are also injection molders. Our engineers make sure that molds are designed, and subsequently built, in accordance with reasonable manufacturability parameters.
We understand our customers best because we know how to design the molds such that it doesn’t create sink marks or other unwanted cosmetic flaws based on customer requirements, and also such that the plastic parts are cost efficient to manufacture.
Richfields also does Moldflow Analysis before any of our mold designs are submitted for customer confirmation. Moldflow Analysis is able to capture possible problems that the manufacturer will encounter if the mold is built as designed. From the analysis, we are able to identify problems before they even come up. From there, we improve on our design and re-design the mold until the best/most reasonable mold design layout is achieved.
With a team of injection molding experts headed by professional team leaders who have more than 20 years of experience in the plastic injection industry, it should be fairly easy to make the decision of hiring Richfields to be your plastic injection mold repair service provider in China.
We provide the following services for new and existing plastic injection molds:
Family Plastic Injection Molds is another cost-efficient solution to today's manufacturers who are seeking to improve their production productivity output without having to sacrifice quality. This is made possible by designing the injection tool so that one mold contains different parts of a product.
The family mold is a kind of multi-cavity mold where each cavity produces different parts of the same product. The parts produced by the different cavities may also be unrelated, they can belong to the same product line or to the same project.
Another reason to use family molds is when the production quantity is not very high in volume. This way, our customers can manufacture more than one part in one production cycle since two or more parts are produced in every shot.
When the different component parts of a product are produced using the same raw plastic material, then all the more reason to use family molds. Not only do you save on expenses in having an additional mold base, you also save on production hours! Time is saved from repetitive mold set up and multiple production cycles.
Richfields' plastic injection molding facilities are equipped to separate the different parts post production. Our production capacity versatility helps customers realize many benefits that not only save on monetary costs but also time and effort.

Richfields Corporation has both the skill and experience in producing plastic parts using cold runner molds. Cold Runner Molds has been used in the plastic industry for a long time now. They are typically less complicated to work with.
Cold runner molds usually uses more material during production, though. This is because in every molding cycle, a plastic part and a runner is produced.
The runner is made of excess plastic material present in every shot. The excess material is removed and may be disposed of or reprocessed. Consequently, the processing time is usually longer. There are also side effects to using reprocessed plastic materials.
The use of cold runner molds is still common in the plastic industry despite possible disadvantages mentioned above. That is because:
Richfields Corporation has designed and built - also repaired - plastic injection molds that use hot runner system for years. Our skill in manufacturing hot runner molds has been very important to our customers.
Hot Runner is usually used for production with high volume, and also with multi-cavity molds. This is so because many benefits are realized when using hot runner molds. Listed below are just some of them:
When you are ready to use a hot runner mold, feel free to Contact Us. Based on experience, our customers would sometimes require a specific brand of hot runner system. We are flexible in this regard and can accommodate the brand of hot runner that will be specified by our customer. Some brands of hot runners that we are familiar with include:
Richfields is able to utilize mold flow analysis programs to ensure that potential processing problems are highlighted at an early stage just before we start manufacturing our plastic tools and molds. If you would like mold flow analysis of your tools please inquire in advance because additional charges may apply. Our equipment, processes and years of experience make our plastic tool and mold manufacturing division a very professional, well-oriented, highly precise factory in China. Some of our strengths include:
Gas Assist Injection Molding is the process in injection molding wherein nitrogen gas is injected through controlled high pressure into the tool during the injection process. Richfields usually uses this process for plastic parts that are considered bigger or thinner than usual, under industry standards. There are a number of benefits to using Gas Assisted Injection Molding process. These include, but are not limited to:
The result is a more sustainable production process due to less stress, wear and tear on the tool. Surface texture is improved because with Gas Assisted Injection Molding, sink marks are eliminated. Contact Us today to know how you can increase production output and save on production costs!
Insert or over molding is used when the design of your products needs to combine materials with different specifications into one finished product. It is used when a single shot is not enough for the complexity of the product. The finished product of an insert molded or over molded part is a single piece with plastic molded around the insert. This is done by incorporating the insert into a tool and then over-molded to form the final part. The insert used in over molding is usually made of metal or plastic. Richfields can do insert over molding for customers who require it in the application of Specialized plastic or metal Inserts and threaded inserts. This technology is actually very cost effective, since it lessens future assembly costs. With the benefits of insert over molding, it has become popular in the market over the years.
Note that not all designs of plastic parts are readily manufactured using over molding, and insert over molding requires more diligence, expertise and experience from the mold makers. We at Richfields have been trained to help you resolve above-standard, complicated and large over-molded parts. We would be glad to assist you from product design up to manufacturing feasibility of your products, making sure your products are manufactured according to their intended use.

Richfields Corporation uses decades of experience in manufacturing unscrewing plastic injection molds. The output is molds that are used for the production of internal threaded plastic injection parts. External threaded plastic injection do no need to be produced using unscrewing injection molds.
Detailed threads on the plastic parts cannot be easily removed from the mold using traditional knock-off, so unscrewing plastic molds have gained popularity not only for its quality but also as a means for cost savings. Unscrewing plastic injection molds can be more complex in design than most plastic injection molds
The molds are operated at high speed to realize faster cycle times. To prevent damaging the threads on the plastic part during production, unscrewing plastic injection molds are being used by the industry.
Unscrewing is widely used for plastic parts that require high volume of output during production. It also prevents damaging the threads on the plastic parts during production. We make unscrewing plastic injection molds to produce high quality parts such as:
