Buy Plastic Molds


A small and simple single cavity plastic injection mold usually costs between $1,000 and $5,000. Very large or complex molds may cost as much as $80,000 or more. On average, a typical mold that produces a relatively simple part small enough to hold in your hand costs around $12,000.

These examples are extreme, but they illustrate the range of costs to anticipate. Your particular part will most likely fall somewhere in between that. At Rex Plastics, our molds average around $12,000.


Material selection is another consideration in determining what plastic injection molds cost. Any plastic product made from fiberglass-filled material, for example, will wear down most common molds. Only a mold made from hardened tool steel can withstand injection molding with fiberglass-filled material.


Nicole,Thank you for the inquiry. A Jackson Pratt bulb is blow molded, not injection molded. Please see this article for more explanation. -injection-molding/the-many-processes-of-plastic-part-manufacturing


Molding plastic is a fun, inexpensive way to create unique pieces or replicas of your favorite items. You may purchase a mold or create your own custom molds out of reusable molding materials, silicone, and or plaster. Cast your mold with plastic resin, wait for it to cure, and then remove the mold to reveal your creation.


Plastic injection molding is the process used to produce low or high volumes of custom plastic parts for commercial and industrial use. From intricate automobile safety components to simple products like business card holders, the applications span a range of industries.


All of MSI customer molds are built right here inside of our Michigan facility. Our mold build area is staffed with experienced designers and machinists using the most modern software and CNC machinery. After customer part designs are finalized and approved for manufacturing our team will design and build robust trouble free plastic injection molds for your production.


Insert molds have a cavity side and core side insert that fit inside of a custom mold base here at MSI. They are a great way for us to offer customers economical tooling at very rapid lead times. The insert style design is great for small and medium size parts that require low quantity part orders or fast delivery of parts.


Even though insert molds are low cost in basic design, they are made with the same high quality materials and components as free standing plastic injection molds and provide the same high quality defect free parts.


Free standing molds, also known as stand-alone molds, provide an all-in-one design. They are built to include the mold base, inserts, and all components needed to be fully functional alone.


A properly designed free-standing mold is built for production inside any SPI standard injection molding machine that is sized properly for the mold. Stand-alone molds have a higher cost, but they are a good choice for multi-cavity production and with high-quantity orders.


The machine injects molten plastic into the mold, where it solidifies to become the final product. The injection molding process is actually a complex process with many variables of speed, time, temperatures and pressures. The complete process cycle for making each custom part can range from no more than a few seconds to several minutes. Below we offer you a very brief explanation of four steps of the molding process.


Before the plastic is injected into the mold, the machine closes the two halves of the injection mold with tremendous forces which prevent the mold from opening during the plastic injection step of the process.


Raw plastic, generally in the form of small pellets, is fed into the injection molding machine at the feed zone area of a reciprocating screw. The plastic material heats up by temperature and compression as the screw conveys the plastic pellets through heated zones of the machine barrel. The amount of melted plastic that is conveyed to the front of the screw is a strictly controlled dosage because that will be the amount of plastic which will become the final part after injection. Once the proper dosage of melted plastic reaches the front of the screw and the mold is fully clamped, the machine injects it into the mold, pushing it into the endpoints of the mold cavity under high pressures.


As soon as the molten plastic contacts the internal mold surfaces, it begins to cool. The cooling process solidifies the shape and rigidity of the newly molded plastic part. The cooling time requirements for every plastic molded part depends on the thermodynamic properties of the plastic, the wall thickness of the part, and the dimensional requirements for the finished part.


After the part is cooled inside the mold and the screw has prepared a new shot of plastic for the next part, the machine will unclamp and open the plastic injection mold. The machine is equipped with mechanical provisions that work with mechanical features designed within the plastic injection mold to eject the part. The custom molded part is pushed out of the mold during this stage and once the new part is fully ejected, the mold is ready for use on the next part.


Many plastic molded parts are fully completed after they are ejected from the mold and simply fall into their final carton to be shipped in, and other plastic part designs require post operations after they are injection molded. Every custom injection molding project is different!


Producing high quality plastic parts can only be achieved by using a high quality built mold. Molds for plastic injection consist of precisely machined components made from various metals such as aircraft grade aluminum or hardened mold steels.


Additionally, mold makers need very expensive tools to perform their job, such as very expensive software, CNC machinery, tooling, and precision fixtures. The amount of time that mold makers need to finish a plastic injection mold can range from a few days to several weeks depending on the complexity and size of the end product.


And finally, the design of your plastic injection mold has a very large impact on its cost. The plastic injection molding process requires enormous amounts of pressure when the plastic is injected into the mold cavities by the machine. Without these high pressures the molded parts will not have nice surface finishes and potentially will not be dimensionally correct.


Whatever type of plastic injection mold you need, we understand that your injection mold purchase will become a significant asset to your business. For that reason, we warranty the production life of molds we build for our customers for the life of their production requirements.


We hope this information helps you better understand plastic injection mold construction and their cost. Remember the quality of your custom plastic parts will first depend on the quality of your mold. Let us quote your next injection molding project and we will work closely with you to make your project a success!


Custom plastic mould, depending on the type of mold being used to make a product. For one, these transparent plastic moulds are used to make a product from aatch of polyethylene terephthalate (PET), and custom plastic mould. If the product is a transparent plastic mould, for the product it is made of, a part of the design that is better.


There are different types of custom plastic molds, logo plastic molds, 3D plastic molds, and logo plastic molds. This type of logo plastic molds is normally used to make a product with a company-shaped design.


On Alibaba.com, you can provide your customer with a wide range of plastic molds, shapes and sizes at wholesale prices so you can choose the product that's suitable for your business. On the other hand, you can stock custom plastic molds with different shapes, sizes, and shapes to your customers' needs, and at wholesale prices from Alibaba.com, you can provide them with the tools they decorate plastic molds for your customers' needs.


When custom plastic resin is available to businesses, it is important to use the mold to a variety of surfaces. Whether you need to make custom plastic resin molds for your car, shop, or other business with a variety of shapes and colors, Alibaba.com offers a variety of custom plastic resin molds available in different designs to suit your needs.


The best scenario will be a vendor that quotes every step in the process accurately and details what each step will entail. Research and design, manufacturing of the molds, testing fees, etc. A quote should outline each piece and how it adds up to the total price. The elite partners in the industry will also suggest changes due to design flaws and potential problems that can occur in manufacturing. Be sure to find a vendor that has your best interest in mind, not just one who offers the lowest pricing. 041b061a72
