HDPE PS POM
Each type of plastic has unique properties that make it suitable for certain applications.
Surface Finishes of Injection Molding
We offer a full set of surface treatments and secondary processing at Machiningtoday. Our main areas of expertise are:
Glossy finishes
Glossy finishes are the most popular type of finish for injection molded parts. They have high reflectivity and can be easily cleaned. However, they are also the most difficult to achieve.
Textured finishes
Textured finishes offer the best resistance to wear and tear. It is created by adding texture to the mold during production.
Painting
We can paint your injection-molded part utilizing any color you desire. We have 3 Painting Lines, and we understand how best to complete production jobs fast.
Matte finishes
Matte finishes have lower reflectivity than glossy finishes but are much easier to achieve. It is a popular choice for products that will be handled frequently, reducing the risk of fingerprints and smudges.
UV Coating
The UV coating is ideal for plastic parts frequently exposed to solar UV rays. It extends the service life and quality of the parts. We have our UV coating line, so we can fully meet the needs of our customers.
In addition to these treatments, we offer other secondary processing options: polishing, silk/pad printing, laser etching, and labeling.

What Is Injection Molding?
Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials.
Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape.
After a product is designed, usually by an industrial designer or an engineer, molds are made by a toolmaker from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part.
The most common material used in injection molding is plastic.
Applications of Injection Molding
Injection molding can be suitable for producing a wide variety of plastic parts and products, including but not limited to the following:
Automotive components
Toys
Household goods
Housings
Brackets
Gears
Single-use medical parts
Electrical connectors
Syringes
Containers
What's Our Process For Injection Molding Services?
Our injection mold-making process involves a series of steps to ensure a successful result.
First, production requirements are determined and arranged. Second, a DFM report is analyzed for feasibility.
Third, the mold is produced, and free samples are created for testing. Fourth, once the client approves the samples, mass production can begin.
Fifth, our professional quality inspection teams will inspect every product. Finally, fast delivery.
By following this systematic process, we ensure that our injection molds meet all necessary criteria and function effectively in the final product.
Injection Molding FAQs
What Are Your Tolerances For Molded Parts?
Molded parts must meet certain dimensional tolerances to function correctly.
Tolerances are determined by the part’s size, complexity, and material.
Generally, our molded parts’ tolerances are between +/- 0.005 inches and +/- 0.010 inches.
How Much Do Injection Molding Services Cost?
The answer depends on many factors, including the size and complexity of the product, the material used, the number of cavities in the mold, and the cycle time.
Advantages of Injection Molding
Injection molding is a popular manufacturing method to produce everything from car parts to kitchen utensils.
One of its major advantages lies in its cost-effectiveness. Injection molding allows for high production speeds and low scrap rates, reducing labor and material costs.
Additionally, this method provides design flexibility as molds can be easily altered to create new products with minimal effort and cost.
Injection-molded products also tend to have uniformity and strength, making them a reliable option for various industries.
Overall, injection molding offers numerous benefits, making it a preferred choice for many manufacturers.
What Is The Difference Between Injection Molding And Plastic Machining?
Injection molding and plastic machining are both methods to create parts and products from plastic. Each has advantages and disadvantages that should be considered when deciding which process to use.
Injection molding injects molten plastic into a mold to create the desired shape.
This process is relatively quick and can create large quantities of identical parts or products.
However, setting up an injection molding operation can be expensive, and the molds themselves can be costly to produce.
Plastic CNC machining is a subtractive manufacturing process that involves cutting away material from a solid block of plastic to create the desired shape.
This process is typically slower than injection molding, but it offers more flexibility in terms of design and does not require the same level of investment in equipment and tooling.
What Is The Difference Between Insert Molding And Overmolding?
Insert molding and overmolding are two different processes used to create plastic parts.
Insert molding is a process where a pre-formed insert is placed into a mold cavity, and then the mold is filled with plastic.
Overmolding is a process where two or more pieces of plastic are bonded together to form one piece.
Insert molding is typically used to create parts with complex shapes or add reinforcement to a part.
Overmolding is typically used to create parts with multiple colors or a soft-touch surface.
While both techniques have advantages, it is important to consider which will be most effective for your needs carefully.
In any case, insert molding and overmolding can lead to stronger and more versatile end products.
