Resin,hailed as"liquid gold"in modern industry,is a core raw material in adhesives,coatings,composites,and electronic encapsulation due to its exceptional bonding,protective,and plastic properties.However,its high viscosity,tendency to cure,and sensitivity to temperature/shear forces make"how to transfer resin stably and efficiently"one of the most challenging issues on production lines.

What is Resin?
Resin typically refers to a class of high-viscosity,viscous substances,either naturally derived(like rosin or amber)or synthetically produced(like epoxy,polyurethane,or unsaturated polyester resins).They are indispensable in these key industrial scenarios:
Precise preparation and filling of adhesives&sealants
Production line transfer of high-performance coatings,inks,and varnishes
Resin injection in FRP(Fiberglass Reinforced Plastic)and carbon fiber composite molding
Precise proportioning and mixing of two-component epoxy systems(e.g.,electronic potting compounds)
Coating applications for food-grade packaging and industrial protective paints

Choose the Right Pump to Solve the Problem!These Critical Factors Must Be Considered:
1.Tackling High Viscosity:Low Speed and Stability are Key
Resin viscosity ranges widely,from syrup-like to near-solid.Transfer requires avoiding high-speed shear,which can cause heat-induced curing or component separation.Cam rotor pumps and other positive displacement pumps deliver a stable,low-speed,uniform output,making them ideal for medium-to-high viscosity resins.Their gentle squeezing action also perfectly handles filled resins(like carbon fiber slurries)with no risk of metal contact contamination.
2.Temperature Control:Maintaining Fluid Flowability
Many resins(e.g.,epoxy,polyester)thicken or even solidify at room temperature.Pump types equipped with heating jackets(oil/electric)or flow path temperature control systems are essential to ensure the resin remains optimally fluid throughout the process.Cam rotor pumps,often integrated with temperature control modules and jacket insulation technology,provide reliable assurance for transferring temperature-sensitive resins.
3.Explosion-Proofing for Harsh Environments
If resins contain flammable solvents like styrene or acetone,or are used in dusty environments(e.g.,paint shops),equipment must comply with explosion-proof certifications(ATEX/IECEx).Selecting pumps with explosion-proof motors and spark-free designs is the core defense to eliminate explosion risks.
4.Combating Chemical Corrosion
Pump body and seal materials must withstand chemical erosion from resins,their solvents,and curing agents.Common combinations include:
Epoxy/Polyurethane Resins→316L Stainless Steel+FKM(Fluorocarbon Rubber)/PTFE(Teflon)Seals
Unsaturated Polyester Resins(containing Styrene)→Hastelloy+FFKM(Perfluoroelastomer)Seals
Acidic Resins/Solvents→Special Alloys(e.g.,Hastelloy C)+PTFE
5.Precision is Paramount:A Milligram's Deviation in Dosing,a Mile's Difference in Product
Especially in two-component potting and mixing reactions,flow accuracy directly determines product performance and yield rates.Metering rotor pumps and servo filling machines achieve ultra-high repeatable accuracy within±5g.Utilizing digital speed control,they easily achieve precise proportional transfer without valve-induced pulsation interference.
