Extensive Guide into The Polyurethane Mold Making Process
At Creatingway, we utilize the polyurethane mold making process to make several components for multiple industries. The material, polyurethane, is very versatile in its use. It creates products weighing from a few grams to thousands of kilograms. Our expert mold making team attribute to its no limit capabilities in the creation of custom designs and inserts. Industries dependent on this polymer include fuel, marine, and manufacturing industries. Here is further insight into its various mold-making processes and uses.
The Common Mold Making Process Used in Polyurethane Include:
- Compression molding
- Injection molding
- Blow molding
- Extrusion molding
- Polyurethane casting
Compression Molding
This process uses an already heated compression material on a heated mold. We then place the material under pressure to ensure all parts get into contact with the mold. Furthermore, we have to ensure the curing part becomes complete. For this to occur, we keep the mold under constant heat and pressure. We recommend the process for simple order at high volume. It is simply fast and cheap when you compare to other molding methods.
Injection Molding
We utilize injection molding to produce many parts ranging from large to small sizes. It uses very high pressure after injecting polyurethane into the mold. Additionally, it offers the advantage of producing strong metal molds at high volume. If your design has intricate shapes, then this is the right process for it.
Extrusion Molding
The extrusion molding process starts with an unformed shape or blank polyurethane mold making process. We then extrude polyurethane through a pre-designed cross-section to create the desired part. Another alternative is forcing the blank through the shaped die. This allows for the creation of even complex final products. We advise the process for designs that require multiple short pieces. Even as an alternate very long products are reproducible as a final product.
Blow Molding
From the name, you could easily guess how the blow molding process works for polyurethane parts. Using the polyurethane, we make a hole at a single end initially. We then proceed to blow a hole through it. This forces the mold to match the dimensions of the desired part. Lastly, we open up the mold and remove the final product after completing the process. Of note is that the process is preferable for creating hollow parts.
Polyurethane Casting
This process shares a similarity to injection molding. However, the difference lies in the volume production capabilities of polyurethane casting. We use silicone to make the mold. Then we inject hot polyurethane into the mold and let it cure for time. From this process, we can make intricate and highly complex products. Additionally, it is ideal for small custom designs, singles units, and various prototypes.
Which Product Machining You Can Use This Process?
At Creatingway, we can derive many components from polyurethane. Some of the products include:
- Rollers, such as idler rollers
- Bushings
- Pipeline components
- Pads
- Blades
- Tubes
- Nozzles
- Gears
- Seals
- Couplings
- Covers and Liners
We understand that all companies have varying needs in their polyurethane quotes. For this sole reason, our engineers are ready to inquire about what type of requirements are most suitable for you. Once we grasp this, we can then proceed to the 3D drawing. We allow clients to constantly review and correct the 3D drawing made to reduce the chances of future defects occurring.
Our engineers are knowledgeable in selecting the most appropriate material composition for your part. We do this keeping in mind what traits the client’s desire. Additionally, we utilize in house tooling to produce prototypes of polyurethane for testing. This allows reliable data collection from the prototype on its physical characteristics.
Benefits of Choosing Polyurethane Molding for Your Project
- The material is surprisingly hard and resilient to the harsh conditions some components shall be exposed to. Polyurethane can easily withstand heat. This is due to its thermosetting properties. Additionally, it is quite resistant to oil, water, and other liquids. It thus fits perfectly for any underwater applications or industries dependent on oil and gas.
- Another unique feature is its flexible bonding capabilities. We can bind polyurethane to metal, plastic, and even wood. This increases your options for products to make from it.
- The polyurethane mold making process provides a wide range of hardness and resiliency figures. We can make it either hard and rigid which is dependent on the client’s desire. Alternatively, it could be pliable and soft for other uses.
- Polyurethane has a shorter lead time from design to prototype when you compare to other molding materials. Such as plastic or metal. Clients can easily get started on their requested projects without unnecessary delays.
- The last important aspect of the material is cost. After the creation of the mold, it easy to make the custom polyurethane product. Moreover, it requires lesser lead time with the right mold making process.
