In the world of packaging, liquids and powders are easy—they flow. But what do you do when your product is solid, irregular, or needs to be counted one by one?
How do you package 50 screws without missing one? How do you wrap a soft croissant without crushing it? How do you bag a heavy door handle without tearing the film?
For manufacturers of Hardware (Fasteners) and Solid Goods (Bakery/Daily Use), standard filling machines won’t work. You need specialized equipment designed for Counting and Horizontal Wrapping.
At Zhenbao Trading, we provide robust automation solutions for the items that are “hard to handle.”
1. The Hardware Headache: Precision Counting for Screws & Nails
If you have ever bought IKEA furniture, you know the frustration of a missing screw. For hardware manufacturers, “Accuracy” is the only metric that matters.
Manual counting is slow and prone to human error. The solution is the Automatic Counting Packing Machine.
The Technology: Vibratory Bowl Feeders
Instead of weighing the screws (which can be inaccurate due to slight weight variances in metal), our machines count them using optical sensors.
Vibration: The screws are dumped into a vibrating bowl. The vibration aligns them in a single file line on a spiral track.
Fiber Optic Counting: As the screws drop off the track, a high-speed fiber optic sensor counts them. 1, 2, 3… 50. Stop.
Dispensing: Once the count is reached, the batch drops into the bag former.
Mixed Kits (The “Furniture Kit” Solution)
Does your product need 4 screws, 2 plastic anchors, and 1 Allen key in the same bag? Zhenbao Trading offers Multi-Bowl Machines. We can set up a machine with 4, 6, or even 10 separate vibratory bowls.
Bowl A counts Screws.
Bowl B counts Anchors.
Bowl C counts Washers. They all dump into the same bucket conveyor to create a perfect “Assembly Kit” automatically.
Noise & Wear Control
Packaging metal nails is noisy and abrasive. Our hardware machines come with Noise-Dampening Enclosures and use PU-Coated tracks to reduce wear and tear on the machine parts.
2. The Bakery & Solid Challenge: Horizontal Flow Wrapping
For solid items that are too big or delicate to be dropped from a height (like bread, soap bars, or hinges), gravity is not your friend. You need a Horizontal Flow Wrapper (Pillow Pack Machine).
How it Works
Unlike a Vertical (VFFS) machine where the product falls into the bag, a Horizontal machine pushes the product into a tube of film.
The Conveyor: You place the product (e.g., a loaf of bread) on a moving belt.
The Forming Box: The film wraps around the product from above or below.
The Seal: The machine creates a “Fin Seal” along the bottom and cuts the ends.
Application: Bakery (Bread, Cakes, Biscuits)
Bakery products are soft and fragile.
No-Crush Handling: Our Servo-Driven Flow Wrappers synchronize the belt speed perfectly with the film speed. The product is never squeezed.
Gas Injection: For sponge cakes or breads, we can inject Nitrogen inside the pillow pack to prevent mold growth, extending shelf life from 3 days to 30 days.
Application: Industrial Solids (Bearings, Hinges, Switches)
Flow wrappers aren’t just for food. They are the standard for packing industrial parts that need dust protection.
Heavy Duty Version: For heavy items like metal door hinges or ball bearings, we reinforce the conveyor belt and sealing jaws to handle the weight and potential impact.
3. Versatility: One Machine, Many Sizes
One of the biggest advantages of the Horizontal Flow Wrapper is its flexibility.
Do you pack a small muffin in the morning and a long baguette in the afternoon?
Adjustable Former: Zhenbao Trading’s machines feature an “Adjustable Bag Former.” You can change the width and height of the bag packaging in minutes using hand-wheels—no tools required.
Memory Storage: The PLC (Touch Screen) can store up to 100 product recipes. Just press “Croissant” or “Whole Wheat Loaf,” and the machine automatically adjusts the bag length and cutting speed.
4. Why Choose Zhenbao Trading for Solid Packaging?
Packaging solid items requires a different engineering approach than liquids.
1. Customized Feeding Systems We don’t just sell the machine; we sell the Feeder.
For biscuits, we offer automatic magazine feeders (stackers).
For soap, we offer automatic pushers.
For hardware, we offer bucket elevators (to lift heavy nails up to the hopper).
2. Anti-Cut Safety What happens if a screw gets stuck in the sealing cutter? It could snap the blade. Our machines feature “No Product, No Bag” sensors and “Misplaced Item Detection.” If the cutter senses a hard object (like a screw) in the seal zone, it instantly stops and reverses, saving your expensive cutter blades from damage.
3. Durability Hardware packaging is tough work. Our machines are built with reinforced frames and hardened steel contact parts to withstand the impact of metal parts drop after drop.
