Types of Plastic Injection Molding
We produce high-quality plastic molded parts of any size or complexity. We use thermoplastics and thermosetting plastics, providing ISO 9001-c or more stringent tolerances.
Injection mold tooling
Get high-quality aluminum and steel injection molds customized to your needs. We achieve tight tolerances of 0.0008 in (0.02 mm) and offer free mold flow analysis. Ideal for mass production.
Overmolding
A cutting-edge process that combines multiple colors or materials in a single molding cycle. This technology produces complex, visually striking parts with seamless bonding and enhanced durability，eliminating secondary assembly.
Insert molding
A custom injection molding process that encapsulates components in a plastic part. It is most commonly used for prototype injection molding designs with threads and holes.
Liquid silicone rubber molding
A flexible prototype injection molding process that produces elastic, durable parts. Get custom prototypes and production parts from 15 days.

Plastic Injection Molding Materials
Plastic injection parts have the most variable options for materials, colors, and configurations. Here are the materials HOMAKE provides to make custom injection plastic parts.
Tooling materials
Before injection molding process starts low or high-volume production, a high tolerance CNC machined tooling is needed.
Plastic materials
Plastic injection molding service comes with a wide range of materials with different properties, including impact strength, rigidity, thermal resistance, chemical resistance, etc.
Additives and fibers
Standard plastic materials may not meet custom injection molding parts requirement. In this case, additives and fibers can be added to improve aesthetic and functional properties, providing additional features for your injection molded parts.
Injection Molded Parts Surface Finishes
We offer SPI surface finishes for injection molded parts. Our injection molding expert is here to help you choose the right finish for your project.
Glossy
A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.
Semi-glossy
B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.
Matte
C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.
Textured
D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Frequently Asked Questions
How much does plastic injection molding cost?
There are many factors that determine the cost of injection molding your custom parts. The three main expenses are tooling, materials and production. Find out how to reduce your manufacturing costs in our injection molding guide.
Who owns the injection mold?
Customers retain ownership of all custom tooling they develop, however, any reusable proprietary components developed by the manufacturing partner (MP) will become the MP’s property. All custom tooling will remain at the MP’s facility for a minimum of two years unless otherwise agreed. If the tooling is inactive after two years, the MP may contact Protolabs Network to determine if the tool must be retained for additional time. Protolabs Network will then contact the customer to make further arrangements. Molds can be transferred to any desired location upon request and at the requester’s expense.
What happens if an injection molding partner leaves our network?
Whenever a manufacturing partner leaves our network, we carry the cost of transferring all molds to another MP in the network, ensuring that your parts get delivered on time.
What is the available capacity/timeline for reorders?
In general, we have the RFQ ready within 24 hours. It takes two days to set up the mold and order and process the materials, and one day for packing and sending the order out to be shipped. The volume of your parts will determine the number of days required for manufacturing.
What ISO certifications do you have?
We work with a network of specialized injection molding companies that have ISO 9001 and ISO/TS16949 certifications. This way you will get the best injection molding service possible.
How long do you store my mold for?
Your injection molding mold is kept at our manufacturing partner facilities for reuse for a minimum of 2 years.
If you would like to reorder from your mold, please contact your account manager or [email protected].
