RenderFact Injection Moulding

Plastic injection molding is the most widely used manufacturing technique to produce mass units of plastic parts that serve industrial and commercial purposes. Plastic injection molding also has the highest range of materials, color, and configuration when put side-by-side with processes like CNC machining or Additive manufacturing. In Injection molding molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.

At Renderfact we specialize in producing high-quality plastic injection molded parts and mold tools. With Advanced material verification and quality processes, we can ensure your tools and parts exceed your expectations. Using the technical maturity to produce high quality custom plastic molded parts for defense, automotive, medical, aerospace and consumer products.

Below are some of the benefits of Injection molding and How it Works!

Advantages of Injection Moulding

Quality and Detail

The high pressure involved in Injection molding means that the molten material penetrates the nook and cranny of the mold before solidification and curing. This allows engineers to design complex parts, inscriptions, details, and elements into their part with the assurance that every part will be made just as they imagined.

Scalability and repeatability

Injection molding can produce thousands to millions of parts that are exact and identical to the master mold tooling.

Cost-effectiveness

An Injection molding tool made from steel can make hundreds of thousands of parts, spreading the tooling cost over a large volume and ultimately lowering the cost-per-part.

Material diversity and options

Injection molding is the most diverse manufacturing technique when it comes to material selection and considerations. Injection-molded parts can be made even stronger by using fillers and composite materials into the liquid resin to improve its tensile strength.

Low-volume manufacturing

Aluminum tooling lower setup and tooling costs, ensuring that injection molding can be used for rapid prototyping and low-volume manufacturing.

Custom Surface Finish

With the proper process optimization techniques, injection molded parts can be ejected ready-to-use or finished in an array of popular or custom methods to ensure that your part look and feel as intended.

INJECTION MOULDING

Renderfact specializes in the use of rapid prototyping and mass-manufacturing techniques to produce high-end plastic injection molded parts and mold tools. Our plastic injection molding process can make custom prototypes and end-use parts in as quick a week. At Renderfact, cost-efficiency is optimized by using aluminum mold tooling that can reproduce thousands of parts and accelerate your product development cycle.

The injection molding process essentially involves loading of resin pallets into a barrel where they will eventually be melted, compressed, and injected into the mold’s runner system. Hot resin is shot into the mold cavity through the gates and the part is molded. Ejector pins facilitate removal of the part from the mold where it falls into a loading bin. Molded parts can be finished in many ways that may cover purely aesthetic finishes or offer some form of protection to the part. Finishes should beautify and enhance the sophistication and functionality of any part.

Materials

Injection Moulding can be done on plastics such as ABS, PP, PVC, PE, HDPE, Nylon, PC, PU, PEEK, PC/ABS, POM, PMMA

ABS

High impact resistance, low-cost & low density.

Polypropylene

Polypropylene (PP) is the most common Injection molding plastic. Excellent chemical resistance. Food-safe grades available.

PVC

PVC is the third most used plastic with all-around good mechanical properties, excellent chemical and weather resistance and good toughness.

Polystyrene

Polystyrene (PS) is the injection molding plastic with the lowest cost. Food-safe grades available. Not suitable for mechanical applications.

Polyethylene

Lightweight thermoplastic with good impact strength & weather resistance. Suitable for outdoor applications.

HDPE

Excellent strength-to-weight ratio, impact and weather resistant.

Nylon

Engineering thermoplastic with excellent mechanical properties and high chemical & abrasion resistance. Susceptible to moisture.

Polycarbonate

High thermal resistance, weather resistance & toughness.

Polyurethane

High impact strength and good mechanical properties & hardness. Thermoplastic with high impact strength and good mechanical properties & hardness. Suitable for molding parts with thick walls.

PEEK

High-performance engineering thermoplastic with excellent strength and thermal & chemical resistance. Used to replace metal parts.

PC/ABS

Blend of two thermoplastics resulting in high impact strength, excellent thermal stability, and high stiffness. Vulnerable to solvents.

POM

Easy to machine. POM is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.

PMMA

UV resistant plastic with good abrasion resistance, stiffness and hardness.

Standard Tolerances

If you do not provide us with your tolerances for Injection Moulding, we use standard tolerances DIN-16901. Tolerances can be greatly affected by part geometry and type of material. Our design engineers will consult you on every part of the project and will try to provide you with the highest degree of precision possible.

Finishes

Renderfact provides surface finishes on all Injection Moulded parts, including Gloss Finish, Semi-Glossy Finish, Matte and textured finishes.

A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces.

B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Products that undergo B grade finishing have a matte surface texture.

C grade finishes use grit sanding stones to produce a rough, uneven surface. Products that undergo C grade finishing have a matte surface texture.

D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.
