Dosing and mixing system for very small quantities – highly precise and repeatable

LV 2/2 series

Possible applications

  • Encapsulation
  • Sealing of tiny electronic elements
  • Seam bonding

The new dosing mixing head LV 2/2 is a high-quality and intelligent precision system for the precise application of smallest quantities.

Typical areas of application are, for example, the encapsulation and sealing of tiny electrical-electronic components or the bonding of small magnets in the rotors of compact e-mobility drives. The new LV 2/2 enables the mixing of resins and hardeners with viscosities from 50 to 20,000 mPas as well as the precise and repeatable dosing of smallest shot quantities from 1.0 to 10 grams. Depending on the pump type used, the user can achieve mixing ratios of 100:5 to 100:200 with the LV 2/2. Other, individual mixing ratios can also be provided on customer request.

Basic equipment

  • Suitable for low viscosity and self-flowing components made of silicone, polyurethane or epoxy
  • Flow rates can be specified between 5 ml to 100 ml/min
  • Adjustable mixing ratio
  • Static mixer or disposable rotary plastic mixer possible
  • Stainless steel tank 3 to 200 l
  • Control: from simple user interface to touch panel
  • Different tube lengths
  • Requires compressed air
  • Power connection: 400 volts
  • Load cell for automatic control of mixing ratio and shot weight

Module elements

A dosing system of the LV 2/2 series can be equipped with the following modules. As a manufacturer of special machines we adapt all machines to the respective process conditions.

Heating

All machine parts, from the container to the hose and mixing head, can be heated to reduce the viscosity of the material – for example, to shorten the pot life or improve mixing of the components. Depending on the application, there are several options available.

Container

  • Jacket heating (adapted to the container)
  • Double jacket (heating with water or oil)
  • Extra agitators for a better heat distribution

Hoses

  • Heated hoses
  • Insulation

Depending on the sensitivity of the material, all possible cold spots must be additionally heated or insulated. Heating cartridges, ring heaters and heating tarpaulins are used in this process.

Mobility

It may be necessary for a plant to be mobile, depending on its size and location/purpose. There are several ways to achieve mobility:

  • Mobile frame
  • Own drive unit
  • Trailer coupling

Refill

To keep the dosing process running longer, we offer refills from IBCs or drums. There are different solutions for the realization of a refill.

Automatic Refill

  • 1st option: Dosing containers are connected to a mobile refilling station (modern connection with couplings without loss of material)
  • 2nd option: Dosing containers are connected directly on the base frame with e.g. an IBC
  • 3rd option: Refill containers are also located on the base frame

The process is controlled via automatic refilling e.g. when a minimum sensor level is reached.

Vacuum Refill

If the material must not come into contact with air, we offer dosing containers in vacuum atmosphere. When refilling, the negative pressure is used to “pull” the material out of the refill containers.

Free Refill

The free refill, also called “free-flow”, uses gravimetry. The material flows from the higher positioned refill container into the dosing containers. No pump is required.
