With our in-house tooling, we can provide immediate feedback and fast lead time. Timely communication is executed with our design engineers in regards to any design improvements by our customers. 3D Design gives our customers a good visual acceptance of our capability and thorough detailing of Design For Manufacturing (DFM), Failure Mode & Effects Analysis (FMEA) & Mold Flow will aid selection of material, gating & cooling options to achieve maximum optimisation.


Our sustainability efforts 



 Sustainability in Plastic Injection Molding Process

With over 30 years of engineering expertise in plastic injection molding, our mold-flow design is specifically engineered by our team of designers to reduce runner wastage and to be energy-efficient. In turn, our customers can have the benefits of lower overhead costs, and a reliable and environmentally responsible supply chain.

We provide an integrated approach to product development that is backed at every stage with exceptional engineering skill, cutting edge technology, and expert guidance. If you require short production runs for a niche market or market research, we can deliver. Our injection molding and tooling services are directed by our expert team with the knowledge and experience that can accelerate your product to market. We are 100% focused on delivering a range of solutions that can be tailored to suit your project requirements, be it large/bumper sized tools or small/rapid tools.


Guaranteed: 500k Shots 


Description: Built for extremely high production. This is the highest priced mold and is made with only the highest quality materials.

Molding surfaces (cavities and cores) must be hardened to a minimum of 48 R/C range. All other details, such as sub-inserts, slides, heel blocks, gibs, wedge blocks, lifters, etc. should also be of hardened tool steels.

Temperature control provisions to be in cavities, cores and slide cores wherever possible.

Over the life of a mold, corrosion in the cooling channels decreases cooling efficiency thus degrading part quality and increasing cycle time. It is therefore recommended that plates or inserts containing cooling channels be of a corrosive resistant material or treated to prevent corrosion.


  • Plastic is molded around a pre-formed non-plastic component, often metal
  • Allows it to be combined into one part with plastic encapsulating the metal, acting as a housing

Two Shot Molding: Comprises of two different polymers, into one molded part

  1. Plastic Injection Molding
  2. Inject liquid silicone rubber (LSR) / different thermoplastic over it

The Difference Between Double Shot Molding and Overmolding - Midstate


Low pressure molding encapsulate electronics parts. It also eliminates the housing otherwise needed to contain the potting material. Its low pressure and low temperature would not damage sensitive circuit boards.

During the molding process, mold-set is relatively cold which can help to decrease the temperature of melted resin without damaging the PCBA or component. This process is widely used for wearables, non-tampering devices and other body wearables.

  • Use of thermoplastic materials with low viscosity
  • Allows overmolding and encapsulation of sensitive circuit boards
  • Designed to have IP-67 Rating: Waterproof


Benefits of Low-Pressure Molding



  • A foaming agent (typically nitrogen gas or chemical blowing agent) is added to a resin polymer as it melts, then injected into the injection molding tool
  • In this process, the blowing agent activates and pushes resin uniformly into the cavity pockets
  • Able to reduce part weight up to 30%


Structural Foam Injection Molding - PSI Molded Plastics


In the in-mold decorating (IMD) process, a preprinted label or film is inserted in the open plastic injection mold and held in place via vacuum ports. In-mold decorating eliminates a post-processing operation by allowing parts to be decorated during the molding cycle. Overall, it enhances manufacturing productivity, overall system cost reductions and greater design flexibility.


Our construction of higher cavity tools and demand for better quality parts has put an increased emphasis on mold-fill balancing. Our fill analysis is a measure of process consistency while injecting.
