KYLT Injection Molding Service:

Plastic parts fast prototyping by CNC machining:

This is for some new testing project, custom just need one or several pieces for testing and check the function.We will make the plastic part by CNC machining, it is fast and high precision,not need making plastic injection molds.

Fast Molded prototypes and low-volume production parts:

For some projects, we need make fast mold to molding plastic parts, after this process, then to make the long life injection mold.

For common plastic, we can make mold directly.

Send us your 3D drawings to , you can got the quotation within 24hrs.

Injection Molding Processes:

Thermoplastic Injection Molding

KYLT can help you design and manufacture tools, dies, and molds for production runs. Full injection molding capabilities including insert molding, overmolding and internal/external threads are available.

Mold Making

As per your 3D drawings, We offer services from design and manufacturing for tools, dies, and molds for prototyping and production runs.

Over molding &Insert Molding

Over-molding and insert molding are two-part injection molding processes where one material is overlaid onto a second substrate part or metal insert to create a single multi-material component.

For over-molding, one material, usually a thermoplastic elastomer (TPE/TPV), is molded onto a second material, which is often a rigid plastic.

Single cavity mold

This type Mold contains only one cavity, per injection make one unit plastic part.

Molds with side-action cores / mold with sliders

It allows for undercuts to be molded. Cores slide out of the part from the side before it is ejected from the mold.

Multi-cavity molds

It allows more parts to be produced per injection, minimizing the unit costs. Multiple identical cavities are machined into the mold.

Family Molds

Several parts which made of same plastic material, are designed into one mold. This allows for the minimization of tooling costs.


Injection Molding Materials:

1. rigid plastic types:

  • ABS : Common thermoplastic with high impact resistance, low-cost & low density. Vulnerable to solvents.
  • Acetal POM [Delrin] : Engineering thermoplastic with high strength, stiffness & moisture resistance and self-lubricating properties. Relatively prone to warping.
  • Acrylic (PMMA) :UV resistant plastic with good abrasion resistance, stiffness and hardness.
  • High-Density Polyethylene (HDPE) : Excellent strength-to-weight ratio, impact and weather resistant.
  • Nylon 6 & Nylon 66: Engineering thermoplastic with excellent mechanical properties and high chemical & abrasion resistance. Susceptible to moisture. Nylon 66 stronger than Nylon 6.
  • PEEK :High-performance engineering thermoplastic with excellent strength and thermal & chemical resistance. Used to replace metal parts.
  • Polycarbonate(PC) : The plastic with the highest impact strength. High thermal resistance, weather resistance & toughness. Can be colored or transparent.
  • Polypropylene(PP) :The most common Injection molding plastic. Excellent chemical resistance. Food-safe grades available. Not suitable for mechanical applications.
  • Polyvinyl chloride(PVC) : Light weight plastic with good mechanical strength and abrasion resistance. Generally used in building and construction applications.
  • PBT
  • PC-PBT (Xenoy)
  • PPE-PS
  • PPS
  • PSU
  • PEI [Ultem]
  • PLA


2. flexible plastic types:

  • Low-Density Polyethylene (LDPE)
  • PC-ABS : Blend of two thermoplastics resulting in high impact strength, excellent thermal stability, and high stiffness. Vulnerable to solvents.
  • Polyethylene(PE) : Lightweight thermoplastic with good impact strength & weather resistance. Suitable for outdoor applications.
  • Polystyrene(PS) :The Injection molding plastic with the lowest cost. Food-safe grades available. Not suitable for mechanical applications.
  • PET


3. rubber-like plastic types:

  • TPE
  • TPV



  • Colorants: Used to color plastics.
  • Carbon fibers: Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle.
  • Glass fibers: Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle. It is more flexible than carbon fibers.
  • Flame retardants: Prevent ignition and inhibits spread of fire.
  • Plasticizes: Increase flexibility and promotes plasticity, reducing brittleness of the material.
