Nylon Cable Tie Factory

In 2008, KST started developing its cable tie product line. By 2010 KST had set up a nylon cable ties manufacturing facility. Today KST manufactures a comprehensive line of nylon cable ties, Mounting, Releasable, Heavy Duty, Markable, Plug, Push, Releasable Push Mount Cable Ties as well as Weather Resisteat UV Cable Ties.

Research and development

KST injection mold and cable tie product factory has an independent research team and a well-equipped laboratory that supports integrated capabilities for material analysis, product design, mold prototype design, mold processing, injection trial production, independent design capabilities, research and development team mentoring, as well as a fully equipped laboratory for verification and testing, that is also UL independent laboratory certified.

Tensile Strength Testing

Materials & Equipment

Plastic products are produced using quality engineered plastics and plastic injection materials from premium suppliers.

In addition, we have invested in precision plastic extrusion and injection machines imported from Japan and Europe, ensuring the stability of production and quality. We have further automated the entire production line allowing us to achieve higher capacity. That means that we can achieve high customization even for an increasing number of small orders.

We use PA66 which is frequently used when high mechanical strength, rigidity, good stability under heat and/or chemical resistance are required.

PA66 pellet resin fro nylon cable ties


From injection mold production, continuous reel product production, carbon embedded injection production, all of our product lines have achieved a high degree of automation including 2.5D CCD quality inspection equipment, and undergo prescribed industry-standard environmental, strength, material, and electrical testing processes.

PA66 Nylon Cable Tie

Innovations in cable tie material and production processes have led to improved structural and tensile strength. Currently, KST has developed the only cable tie product on the market made from PA66 material, that meets the pull force requirements set by the UL 62275 standard, which requires testing to -20 degrees for mounting and -40 degrees in operation.

Certified: DNV, ABS, UL, ROHS
Material: PA66 (Nylon)
Flammability Rating: UL 94V-2
Max. operating temperature up to 120℃

Step 1

Raw Material

ISO 14001

Raw material Input Quality Control (IQC) includes dimensional check, visual inspection of raw materials, RV (Reduced Viscosity), MI (Melt Flow Index), examine and determine mechanical physical strength.

Step 2

Retrieve Mold and Raw Materials from storage

Materials and molds are managed by the ERP system and picked out of the warehouse via an integrated automated storage retrieval system.

Step 3

Material Drying

The central computer system automatically controls the raw material mixing, and temperature drying setting, to ensure the stability of the moisture content of the raw materials.  PA66 (Nylon) is often used because it provides high mechanical strength, rigidity, good stability under heat and chemical resistance.

Step 4

Pneumatic Pressure Delivery System

Each injection machine communicates with the central computer system to automatically monitor the required material that is delivered through the pneumatic conveyor delivery system.  By, design, it is scalable, transporting PA66 from a single source feeder to multiple destinations. 

Step 5

Injection Molding

The plastic pellets are heated, and after they are melted, they are injected into the molding. During the injection molding process, the plastic can be reinforced with embedded carbon for additional tensile strength.  KST has invested in high-speed molding machines from Japan and Europe to produce superior quality nylon cable tie products.

Step 6

Automatic CCD Inspection machine

The finished product passes between vibrating plates, and the CCD Inspection machine automatically detects visual imperfections. The Automation Department engineer codes programs to detect abnormalities in products through PLC (programming logical controller) signals and automatically returns a product that is below tolerance to the defective products area.

Step 7

Automatic Cutting

The finished product in the mold is cut and separated from the runner material through an automatic cutting machine, and automatically counted by the infrared sensor. Every 100 pieces is picked by the robot hand gripper and put into the automatic packaging machine.

Step 8

Automatic Water Spray

Nylon Cable Ties are bundled, automatically inserted into a plastic bag, and sprayed with water to allow the cable ties to continue to cure inside the packaging and ensure the stability of the moisture content of the finished product.

Step 9


Linked to the production order management system in ERP, the label printing system can fetch product specifications and customer shipping information from the synchronized database. It can print product labels for bags, boxes, cases, pallets, crates, and custom documents efficiently.

Step 10

Finished Product is returned to Inventory

When the product attains the target moisture, Personnel will scan the ID bar code and the ERP system will transport the finished product into the automatic storage and retrieval system.

Step 11

Outgoing Quality Control (OQC)

Outgoing Quality Control (OQC) shipping inspection conducted to confirm product appearance, function, packaging, marking, and quantity. Cable ties are placed on a conveyor belt and carried to packaging operations for inspection. Here they are placed on weighing devices and then sensor counters to double-check that the packing quantity is correct. 

Step 12

Loading and Shipping

The unloading of incoming raw materials from containers and loading of outgoing finished products are synchronized to facilitate good logistical practices.
