PLASTIC INJECTION MOLDING
Plastic Injection Molding Services
Plastic injection molding is a manufacturing process used to produce accurate and repeatable plastic components. Molten thermoplastic resin is injected into a mold cavity, where it cools and solidifies into the required shape.
At HordRT, we provide integrated support from DFM analysis and tooling development to mold trials and production molding. Our capabilities cover prototypes, low-volume production and repeat manufacturing, with no minimum order quantity.

INJECTION MOLDING PROCESS
How Custom Plastic Injection Molding Works
A controlled molding process turns thermoplastic resin into accurate, repeatable components through preparation, injection, cooling and inspection.
Mold Installation
The mold is installed and the required process settings are prepared.
Material Feeding & Melting
The selected resin is prepared, fed into the machine and heated to the correct processing temperature.
Plastic Injection
Molten plastic fills the mold cavity under controlled speed and pressure.
Holding & Cooling
Pressure and cooling time are controlled while the molded part solidifies.
Ejection & Inspection
The finished part is released and inspected against the approved requirements.
ISO Class 8 Cleanroom Injection Molding
Our 720 m² cleanroom provides a controlled manufacturing environment for injection molded parts requiring enhanced cleanliness, process consistency and contamination control.

INJECTION MOLDING DESIGN GUIDANCE
Design Better Parts.
Reduce Tooling Changes.
Review the molding fundamentals before tooling begins. Early attention to wall thickness, draft, structural features and mold direction helps reduce defects, rework and unnecessary cost.
Wall Thickness
Keep sections consistent for balanced filling and cooling.
Draft Angles
Support clean ejection and protect cosmetic surfaces.
Ribs & Bosses
Add strength without creating excessive thick sections.
Parting Lines & Undercuts
Plan mold direction before complex tooling is required.

Production Materials Real resins for validation
01 What information do you need to quote my project?
Please send your 3D CAD file, preferred material, required quantity, surface-finish requirements, tolerances and any relevant 2D drawings. If some details are not yet confirmed, our engineering team can recommend practical options during the DFM review.
02 Is there a minimum order quantity?
No. HordRT supports prototype, bridge and repeat production without a fixed MOQ. We select the tooling approach around your expected volume so you do not overinvest before demand is proven.
03 How long does an injection mold take to build?
Typical rapid tooling lead time is about 10–15 days after design approval. Complex geometry, multi-cavity tooling, special steels or demanding cosmetic requirements may require additional time. A project-specific schedule is included with the quotation.
04 Can you help select the right plastic material?
Yes. We evaluate mechanical strength, operating temperature, chemical exposure, appearance, regulatory needs and cost. Our material range includes general-purpose plastics, engineering resins, elastomers, glass-filled grades and selected medical-grade materials.
05 Can you produce prototypes with production-grade materials?
Yes. Rapid injection molding allows you to validate form, fit and function using the intended production resin. It is useful when machined or 3D-printed prototypes cannot accurately represent molded-part performance.
06 Who owns the mold after the project is completed?
Unless otherwise specified, our injection molds and pressure die-casting molds are built using HordRT’s shared Modular Unit Die (MUD) mold bases and standard components. These shared mold bases and components—including hot sprue or runner systems and hydraulic cylinders—remain the property of HordRT. After full payment, the customer owns all custom inserts, custom components and related 2D/3D drawings listed in the quotation. If a complete standalone mold must be transferred from HordRT, the additional mold base and components will be quoted separately.
07 How do you control part quality during production?
Quality planning begins with DFM and drawing review, followed by incoming-material checks, first-article inspection, documented process control and final inspection. Depending on the project, inspection may include CMM measurement and blue-light scanning.
