Extruder Types
Single-cavity, Multi-cavity, and Family Mold Options:
The mold may feature either one cavity or multiple cavities, each of which can be used to create a single part. A family mold is a mold that combines different parts into the same mold base.
Gas-Assist Molding:
A process where an inert gas is injected into the melted plastic pushing it further into the mold and resulting in hollow parts. This allows for complex and intricate designs to be made.
Insert Molding:
Involves adding inserts, particularly metal, into an injection-molded part. Placing the insert within the mold cavity occurs before molten plastic injection. Consequently, on cooling, the insert becomes permanently combined with the plastic part.
Overmolding:
A method of molding two or more different materials into one plastic part at one time. Commonly employed for molding a rubber-like plastic (such as TPE) onto another custom plastic component.

Part Review Analysis:
The mold may feature either one cavity or multiple cavities, each of which can be used to create a single part. A family mold is a mold that combines different parts into the same mold base.
Reverse Engineering:
Custom Plastics can advise on current designs to determine if they will achieve the customer’s needs and meet the standards for manufacturing.
Streamline Sub-Assemblies:
Streamlining sub-assemblies is crucial for cost-effectiveness, competitiveness, and future improvements. A smooth and optimized manufacturing process saves labor and time, enabling better customer satisfaction.
Material Selection
Extensive Analysis and Selection of Resins:
Progress in polymer science has led to the creation of a wide range of resins to choose from. Our goal is to meet customer requirements by identifying alternative resins that are more readily available and cost-effective.
Experts In Plastics To Advise Best Resin For Your Project:
Custom Plastics thoroughly evaluates the mechanical requirements, chemical compatibility, environmental suitability, performance, and material shrinkage in order to provide a comprehensive analysis. Based on this analysis, suitable options are then recommended.
Resin Partnerships:
Custom Plastics maintains strong alliances with premier resin suppliers across the nation. With a rich legacy spanning over six decades, we have garnered expertise in utilizing certified commodity and specialty resins that align with our rigorous manufacturing benchmarks.

Materials
Materials We Work With
ABS
Acrylic
Acrylic
LDPE
ABS is a tough, stable thermoplastic known for its resistance to impact and heat. The surface of ABS is typically shiny and bright.
A glass alternative, Polymethyl Methacrylate has high tensile and flexural strength, UV resistance, and transparency.
A glass alternative, Polymethyl Methacrylate has high tensile and flexural strength, UV resistance, and transparency.
Compared to HDPE, the molecules of LDPE are more branched out, making the thermoplastic weaker but more flexible. LDPE can be translucent or opaque.
MDPE
PVC
PC
PP
With properties between HDPE and LDPE, MDPE has excellent shock and drop resistance properties. MDPE is less dense than HDPE but stronger than LDPE.
Polyvinyl Chloride is one of the most versatile plastics. It comes in two types—rigid and flexible—and is dense with good tensile strength.
Polycarbonates are a group of polymers that contain carbonate groups within their chemical structures. Polycarbonates are used in a wide variety of applications typically where impact resistance and transparency are required.
Polypropylene is a widely used thermoplastic popular for its high melting point and low level of electrical conductivity. On top of this, Polypropylene does not break down easily but is resistant to cracking and stress.
PETG
HIPS
PU/TPU
TPU
A transparent material, PETG is a common substitute for PVC that provides similar properties with the additional glycol modification.
Both transparent or colored, Polystyrene provides good elasticity and flexibility. It can be manufactured as a solid or foam.
Polyurethane boasts excellent elasticity and clarity and also provides protection from grease, oil, or other damage.
TPE is a physical mix of polymers . It can be stretched to twice its original length and still return to its original shape. TPE is similar to TPR, but is more soft and flexible.
