If you work in plastics manufacturing, you already know how crucial every detail of the injection molding process is. From tooling design to material flow — every small element affects product quality, speed, and consistency.
But there’s one part of the process that often gets overlooked until it becomes a problem: part separation.
That’s where a high-quality Injection Molding Part Separator comes in.
At LXG Injection Molding, we design and deliver durable, efficient, and easy-to-integrate Injection Molding Part Separators that help you maintain production flow, minimize defects, and protect molded components during handling.
Let’s break down what these separators are, how they work, and why choosing the right one can transform your molding line efficiency.

What Is an Injection Molding Part Separator?
An Injection Molding Part Separator is a specialized piece of equipment designed to separate finished molded parts from runners, gates, or sprues after they’ve been ejected from the mold.
Think of it as the “sorting system” that ensures only good, finished parts move forward — while excess material or defective pieces are removed automatically.
Instead of manually picking through hot plastic parts or relying on inefficient sorting, an Injection Molding Part Separator automates this process, improving productivity and worker safety.
At LXG Injection Molding, we build separators that can be customized to your production line — from small prototype setups to high-speed mass-production environments.
2. Why Do You Need a Part Separator in Injection Molding?
If you’re molding plastic components daily, the challenges below will sound familiar:
Mixed piles of parts and runners
Hot parts sticking together or deforming
Increased operator labor and inspection time
Higher scrap rates and slower cycle times
A properly designed Injection Molding Part Separator solves all of this by:
✅ Automatically separating good parts from scrap material
✅ Protecting parts from deformation and scratches
✅ Reducing human handling (and therefore, labor costs)
✅ Maintaining consistent production flow
It’s not just an accessory — it’s an essential part of a professional injection molding setup.
3. How Does an Injection Molding Part Separator Work?
While the design can vary depending on your production scale, the basic principle is simple.
After each cycle, molded parts and runners are ejected together from the mold. These fall onto a rotary or vibrating separator. The separator then sorts components based on size, weight, or geometry.
Rotary Drum Separators: Use rotating screens or mesh to separate smaller parts from larger sprues.
Vibratory Separators: Rely on vibration and screen layers to sort parts efficiently.
Conveyor Separators: Transport parts away from the molding area, automatically sorting as they move.
At LXG Injection Molding, our part separators are built with high-precision aluminum frames, adjustable screen designs, and smooth-motion drives to ensure gentle yet effective separation — even for delicate or complex parts.
4. Key Features of LXG Injection Molding Part Separators
When you invest in an Injection Molding Part Separator from LXG Injection Molding, you’re not just buying a tool — you’re upgrading your production efficiency.
Here’s what makes ours stand out:
a. Adjustable Separation Design
Our separators come with adjustable screen angles, drum speeds, and vibration levels, allowing you to fine-tune performance for each product type.
b. Durable Construction
Built from high-grade stainless steel and aluminum, LXG’s part separators are corrosion-resistant and easy to clean — perfect for long-term, continuous use.
c. Gentle Handling
Smooth rotational motion prevents scratching or deformation, especially for glossy or soft plastics.
d. Compact and Modular
We know floor space is precious. That’s why our Injection Molding Part Separators are compact, modular, and easy to integrate with existing conveyor systems or molding cells.
e. Quiet Operation
Noise reduction features ensure a safer, more comfortable working environment — even during high-speed cycles.
5. Types of Injection Molding Part Separators
Different applications call for different setups. At LXG Injection Molding, we offer a full range of separator types:
1. Rotary Drum Separators
Perfect for high-volume production. Parts and runners fall into a rotating drum with precisely sized holes, allowing finished parts to drop through while runners remain inside.
2. Vibratory Separators
Best for mixed-size products or delicate parts. Vibrations move items across a mesh surface where they naturally separate by size and weight.
3. Magnetic Separators
Ideal for molds that include metal inserts or embedded hardware. Magnets capture metallic pieces safely and efficiently.
4. Air-Blow Separators
Used for lightweight parts where air pressure can blow away smaller or unwanted fragments.
5. Custom Separator Systems
Our engineering team can design custom Injection Molding Part Separators to match your specific part geometry, cycle times, and output requirements.
6. Benefits of Using LXG Injection Molding Part Separators
Still wondering if upgrading your system is worth it? Here’s why our customers keep choosing LXG:
✅ Improved Efficiency
Separation happens in real-time, cutting idle time between cycles.
✅ Reduced Labor Costs
Automation minimizes manual sorting and reduces operator fatigue.
✅ Better Part Quality
Gentle handling and consistent separation reduce scratches, warping, and contamination.
✅ Faster Cycle Times
Less downtime means faster throughput — critical for mass production.
✅ Higher Safety
Operators no longer need to handle hot parts or sharp runners manually.
✅ Cost Savings
Less scrap, less rework, and less labor all contribute to lower operational costs.
✅ Scalable & Customizable
Whether you’re running small prototype batches or large-scale production, our systems can grow with your business.

9. How to Choose the Right Part Separator for Your Production Line
Not all separators are created equal. When choosing the right Injection Molding Part Separator, consider:
Part Geometry: Round parts require different mesh sizing than flat or irregular shapes.
Material Type: Soft thermoplastics need gentler handling than glass-filled resins.
Production Volume: Higher throughput lines need rotary or automated separators.
Space Constraints: Compact systems work best for limited floor space.
Automation Level: Consider integration with conveyors, robots, or inspection cameras.
