Dynamics of Contract Manufacturing
Facilities that produce and package products on behalf of other companies without having their own brand are referred to as Co-packers / Contract Manufacturers.
In the world of contract manufacturing, there are no fixed rules. On Monday, they might be packaging 50-gram portions of oatmeal; by Wednesday, the same machine could be handling 1 kilogram of cat food, and by Friday, it may need to package liquid detergent. This variability determines the most critical feature sought in a packaging machine: Flexibility and Quick Changeover.
3 Fundamental Elements to Consider in Flexible Machinery Investment
For contract manufacturers, the return on investment (ROI) of a packaging machine depends on how short the downtime is.
1. Tool-less Changeover: When transitioning from one package size to another (for example, from a 10 cm width to a 15 cm width), it is a significant waste of time for the operator to search for a wrench or an Allen key set. In modern machines, the Forming Tube, sealing jaws, and sensor settings are changed "tool-less" within minutes thanks to quick-release mandrels and pneumatic clamps.
2. Multi-Dosing Unit Compatibility: A truly flexible VFFS (Vertical Form Fill Seal) machine is not picky about the filling unit attached to it. Dr Mach chassis are designed with a "Plug & Play" logic:
- You can attach an Auger for powder products.
- You can connect a Multihead Weigher for granular products.
- You can integrate a Piston Volumetric filling pump into the same chassis for liquid products.
3. Recipe-Managed PLC Screen: Every product and packaging film has a different sealing temperature, draw speed, and target weight. Instead of entering these values manually during every format change, "Recipe-1: Oatmeal 50g" is selected via the HMI (Human Machine Interface), and all motors and heaters in the machine automatically adjust themselves according to that product.
Servo Motor Technology for Increasing Profitability
Old-generation pneumatic (air piston) machines have mechanical limitations. However, in Full-Servo machines, infinite flexibility is provided because moving mechanisms are managed by independent software. For example, the same machine can produce both a pillow bag and a gusseted bag without any hardware changes.
Frequently Asked Questions (FAQ)
Q: Are short-runs profitable in contract manufacturing? A: If your machine's format changeover time takes 1-2 hours, it is not profitable. However, since transitions are reduced to 15 minutes in Dr Mach machines designed with the SMED (Single-Minute Exchange of Die) principle, you can take on 4-5 different small batches per day and rocket your profitability.
