Custom plastic part manufacturing designates a set of fabrication methods used to manufacture a custom parts made out of various plastic materials. At Norck, we manufacture custom plastic parts for a wide range of industries including:

   -  Medical: orthosis and prosthesis devices
   - Industrial: jigs and fixtures
   - Hardware: customized hardware parts
   - Aerospace & Automotive: Prototypes, interior command units
   - Robotics: Robot's bodies
   - Consumer products: Enclosures and product's bodies
   - Hardware: Plastic bearings, handles, covers
   - Education: Conceptual prototypes

At Norck we believe that custom plastic part manufacturing offers many advantages over medium and high-volume production:

• Lower production costs: A custom part might cost more per part than medium or high-volume production. But it is cost-effective for two reasons:
   -  It doesn’t require a big budget for development, tooling, and fabrication
   -  It can be manufactured in smaller quantities

• Highly customizable: As the name suggests, a custom plastic part is customizable. Your product can be as custom as you can imagine.

• Convenient for startups and small businesses: Custom plastic part manufacturing is ideal for startups and small businesses since it helps them turn any idea into a tangible product and test the market before diving into mass production.

There are several manufacturing processes Norck follows to produce custom plastic parts. These processes can be divided into three broad categories:

1.  Additive manufacturing

• Plastic 3D Printing: It is a process used to produce custom parts by printing layers of plastic materials. Plastic 3D Printing uses multiple methods to create custom plastic parts, and it is evolving. At Norck, we offer numerous 3D printing methods, such as FDM, SLA, SLS, Polyjet, Carbon DLS, and HP multijet fusion.

   • Used plastic materials include:
   -  ABS Like (resin)
   -  PC Like (resin)
   -  PP
   -  PP Like (resin)
   -  Nylon
   -  Silicone
   -  TPU

   • Application: It is mainly used in the earliest stages of product development and can be used in conceptual models, functional prototypes, tooling, electronics, jewelry, and medical industries.

   • Advantages and disadvantages:
+ Cost-effective process with a vast choice of plastic and elastomeric materials
- Weaker results compared to other plastic manufacturing processes.

2. Subtractive manufacturing

   • CNC machining: CNC machining (Computer Numerical Controlled machining) designates a process that uses a computer to control the trajectory of the machining tool. It employs many machining techniques, such as milling, drilling, and cutting.

   • CNC Turning: This method uses a lathe to turn workpieces at high speeds and a tool with a special shape to remove layers of material from the workpiece. The workpiece shape is generally revolutionary. If the workpiece is long enough, an extra part is used to support the weight of the workpiece.

   • CNC Milling: Milling is a process that uses a rotating tool to remove material from the fixed workpiece. There are two types of milling, horizontal and vertical milling.

   • Used materials are:

   • CPVC
   • HDPE
   • LDPE
   • PC
   • PP
   • PVC
   • PS
   • PEI
   • PET
   • PMMA
   • PTFE
   • PS
   • Nylon

   • Applications of subtractive manufacturing: It is widely used in various sectors such as Aerospace, automotive, medical, and oil and gas. It makes gears, jigs and fixtures, and elastomer seals.

   • Advantages and disadvantages:
+ Accurate process with lower fabrication costs
-  Manufacturabilité is limited to simple shape

3. Formative manufacturing

   • Injection molding: In injection molding, molten plastic pellets are fed into a mold cavity under high pressure. After the plastic solidifies, the mold is opened, and the part is ejected. Mold is made from hardened steel and contains the shape of the part to be molded. The Injection molding process is used for high and medium-volume production.

   • Urethane Casting: Urethane Casting is a plastic molding process used to duplicate a master component submerged into liquid silicone. After the silicone mold solidifies, it is opened, and the master part is extracted. The mold is closed and injected with urethane, then gets heated to harden the urethane and extracted. Urethane Casting is used for low-volume production.

   • Liquid silicone rubber molding: It is a rubber molding process that injects silicone and color into a mold, which is heated to solidify, then the part gets ejected. The mold is made from hardened steel and contains the body of the part to be molded. The liquid silicone rubber molding process is used for high and medium-volume production.

   • Application: It is widely used in various sectors such as Aerospace, automotive, medical, oil, and gas. It is used to make enclosures, handles, switches, jigs, and fixtures, electronics.

   • Advantages and disadvantages:
+ Accurate process with a vast choice of materials and colors
+ lower fabrication costs
- High cost of tooling and often long cycle time

   • Waterjet, laser, and plasma cutting: It is a set of cutting methods that use heat or water to cut through almost any type of material to produce a part or product.

   • We offer the following finishes for custom-manufactured parts:

   - Textures
   - Surface finish (smooth or matte)
   - Inserting threads
   - Pad printing
   - Laser engraving
