General Instructions Regarding Working withApplication Materials

Definition of TermsApplication materials can be e.g. thermoplastic hot melt materials, adhesives, sealants, liquid adhesives and similar application materials. They arereferred to as materials.

NOTE: The materials that may be processed with your Nordson product aredescribed in the manual under Intended Use and Unintended Use. When indoubt, please contact your Nordson representative.

Manufacturer InformationMaterials may be processed only when the manufacturer's product descriptions and Safety Data Sheets (MSDS) are observed.

They provide information, amongst other things, on correct processing of theproduct, transport, storage and disposal. Information regarding reactivity andpotentially hazardous decomposition products, toxic properties, flash points,etc. can also be found there.

LiabilityNordson is not be liable for danger or damage resulting from the materials.

Risk of BurnsThere is a risk of burns when handling heated materials. Work carefully andwear appropriate protective clothing/equipment.

Introduction0‐4

HMI02_EN_C-0108 � 2014 Nordson Corporation

Vapors and GasesEnsure that vapors and gases do not exceed the prescribed limits. If necessary, exhaust vapors and gases and/or provide sufficient ventilation of thework space.

SubstrateThe substrate should be free of dust, grease and moisture. The suitable material, optimum working conditions, and possible pre‐treatment of the substrate must be determined by testing.

Processing TemperatureWhen materials require heating, adherence to the prescribed processingtemperature is imperative to ensure the quality of the application. It may notbe exceeded! Overheating can cause material coking or cracking, resulting inmalfunctioning or unit failure.

Material should always be melted gently. Extended, unnecessary temperature load should be avoided. The temperature should be reduced duringbreaks in work. The temperature in the tank should be attuned to the materialconsumption. Thus it is close to the prescribed processing temperature forhigh material consumption and lower for lower consumption.

When materials are processed cold, take into consideration the shear heatand the ambient temperature; cool if necessary.

Function

The following figure illustrates the basic method of operation of a pistonpump within a complete system.

Adhesive is to be applied to a substrate (7). The transport belts (8) conveythe substrates. When the leading edge of a substrate reaches the photo cell(10), the beam of light sent is reflected and the program is started. Thecontroller compiles all the data according to the speed of the productionmachine. The encoder (4) is mechanically connected to the transportequipment via a gear and supplies one pulse per mm. The control unitevaluates all the data and establishes the point at which the applicators (5)must be activated.

The piston pump (12) is connected to the compressed air supply (1). Itoperates continuously and pumps the adhesive from the adhesive reservoir (11) to the applicators (5).

A current between 0‐20 mA is supplied from the control unit (3) to theproportional pressure control valve (2). The strength of the current isdependent on the speed of the production machine. The strength of thecurrent determines how far the proportional pressure control valve (2) shouldbe opened and the adhesive pressure regulator (9) opens accordingly. Theadhesive flows to the applicators (5) and is applied to the substrate. Thelength of the application is defined by the controller’s program.
