Laboratory Extruder
Industrial Laboratory & Pilot Scale Extruders for Plastics R&D
Flexible, Custom-Engineered Twin-Screw & Single-Screw Test Lines
Processing Scope Notice: Kairong Machinery designs lab extruders exclusively for the plastics and polymer processing industry (Universities, R&D Labs, and Factory Recipe Testing). We do NOT manufacture equipment for food, pharmaceutical, or medical processing.
Why Work With Us for Your Lab & Pilot Extrusion?
Unlike massive manufacturers who reject small custom requests, we treat every lab extruder project as a collaborative engineering solution:
- Tailored Customization: Have a unique process idea? We actively work with you to engineer customized feeding setups, specialized die heads, or non-standard pelletizing lines.
- Industrial Durability: Our lab machines (φ20mmscrew diameter and up) are built with standard durable and wear-resistant screw and barrels and drive systems, offering true industrial stability rather than delicate, low-durability lab gadgets.
- SmoothProcess Scale-Up: Processing data, torque ratios, and thermal behaviors derived from our TSE-20/TSE-30 machines can be reliably translated to full-scale commercial production lines.
- Siemens Touchscreen (HMI) & Data Logging: Equipped with intuitive Siemens HMI touchscreens for easy operation, precise PLC control, and real-time recording of temperature, pressure, and torque data for your R&D reports.
Our Lab Machine Model Range
We categorize our laboratory and pilot extruders by real industrial capacity requirements:
1. Co-Rotating Twin Screw Lab Extruders (Primary R&D Range)
- TSE-20 Line (Min. Screw Dia.20mm): Our standard starting model for small-batch color matching, additive testing, and university polymer teaching labs. (Output: approx. 5-10kg/h).
- TSE-30/35Line ( 30/35mm): The ultimate pilot-scale workhorse. Widely used by compounding plants for trial runs, recipe verification, and sampling before mass production. (Output: approx. 10-30kg/h).
2. Single Screw Lab Lines & Desktop Test Units
SJ-25 / SJ-35 Single Screw Lines
If your project specifically requires a compact single-screw setup for straightforward trial pelletizing (such as processing specific plastic waste or basic raw materials), we can fully custom-build a small single-screw line to your specs.
Desktop Test Extruders
Need a micro plug-and-play desktop unit? We source and integrate reliable mini-desktop extruders upon customer demand.
3. Tailored Downstream Pelletizing & Space-Saving Systems
For laboratory testing, water ring die-face or underwater pelletizers are rarely necessary. Most R&D tests run perfectly with Strand Pelletizing (Water-Strand or Air-Cooling Strand). Based on real factory constraints, we offer two highly popular lab configurations:
All-in-One Space-Saving Integrated Unit (Water Trough + Air Blower + Pelletizer)
The Problem: Most university labs and factory R&D centers face strict space limitations and cannot fit a standard 10+ meter production line.
Our Solution: We engineered a compact Integrated Downstream Unit that combines the water cooling trough, air-knife blower, and strand pelletizer into a single mini-frame. This dramatically reduces the line’s footprint—fitting your entire line within just a few meters.
Dual-Option Flexible Setup (Water-Strand + Air-Cooling Strand)
The Problem: R&D teams often test diverse recipes—some polymers require water cooling, while water-sensitive biopolymers or high-filler materials must stay completely dry.
Our Solution: You can pair one primary lab extruder with two interchangeable strand lines (one standard water-strand set, and one air-cooling conveyance belt with air-knife pelletizing). This gives your lab maximum flexibility to test any formulation on a single extruder.
Frequently Asked Questions (FAQ)
Q1: What is the minimum output capacity and screw diameter you can manufacture?
By Output: Depending on your material's bulk density and melt index, our lab lines can achieve an output as low as 0.5kg/h.
By Screw Diameter: Our absolute minimum screw diameter experience goes down to 16mm. However, because 16mm requires non-standard, fully customized components, its manufacturing cost is significantly higher. For the best balance of cost, durability, and practical R&D performance, our TSE-20 remains our most popular and cost-effective bestseller.

Q2: Can your extruders be used for non-plastic materials?
While our machinery is strictly optimized for plastics processing, we do have clients using our extruders for non-plastic applications. However, this requires the client to have prior processing experience and provide us with specific technical requirements—such as screw configuration, targeted temperature, or specialized screw/barrel material (e.g., 304 Stainless Steel). As long as you provide clear specs, we can fully custom-engineer the machine for you.
Q3: How is your machine quality and long-term after-sales support?
Proven Client Trust: Many of our long-term industrial clients started their very first order with us for a lab extruder. After verifying our machine's performance, they expanded their factories with our full-scale production lines.
Standardized Spare Parts: We have been in the extrusion industry for decades. Our lab extruders are built using standard, widely accessible industrial components. If a wearable part ever needs replacement years down the road, you can easily source it locally or from us. You will never have to worry about a broken custom part making your machine obsolete.
