CAPABILITIES
Overmolding Service
Industries including robotics, medical and automotive use overmolding for manufacturing aesthetically pleasing products or to reduce the assembly line stations. Overmolding offers a more convenient solution for injection molded products with two or more materials.
Prolean’s overmolding services offer all the different combinations for overmolded parts with a wide range of materials to choose from.

What is Overmolding?
How to Order Parts?
Get a free quote from a real engineer; once we receive your design, our engineer will review it and send you a quote as fast as one hour.
Get A Quote Immediately
Upload your design or email our engineer directly and get your quotes as fast as one hour.
Start Production
Your parts will be made once your orders are confirmed. Besides, you will get real-time order updates of the production status from our order tracking system.
Receive Your Part
After all parts pass QC inspection, they will be well packed from transportation accidents. Then, your custom parts are delivered straight to your doorstep.
Overmolding has one primary advantage. One machine can generate multiple pieces of the part directly on each other. This reduces the number of machines and assembly line stations required which saves a large amount of time and money.
Overmolded parts have a broad range of applications due to their composite nature. Grips, seals, insulation, and vibration-absorbing layers are often over-moulded on products.

Finishing Options For Overmolding Product
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
PTFE (Teflon) Coating
The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Smooth machining
Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.
More
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

I am especially pleased with how you provided the overmolding prototypes for adjusted design each time before full-scale production. Thank you!
-Jonathan Meyers, Senior Prototyping Engineer at InnovateMold Solutions
Excellent grips on my tool holders and I am fully satisfied with the results. I don’t think anyone will meet the collaboration spirit of Proleantech’s Engineers.
-Emily Carter, Director of Product Development
Our remote control housings arrived today! All of them are according to specifications and surface polishing looks nice too! We will surely collaborate in the future.
-Mark Johnson, Lead Manufacturing Engineer at Prototype Edge
These polypropylene toothbrushes look great and perfectly functional as we needed. We will customize the surface texture and color next time. Thank you for the timely delivery.
-Sarah Thompson, Head of R&D
We received the insulated cable assemblies, and they are perfect! The flexibility and durability are exactly what we needed. Your team’s dedication and clear communication has been invaluable.
-Michael Harrison, CastForm Technologies
