Hi,
create a string with the whole expression before you call ToExpression.
parameters = "{a,-1,4},{b,0,20}";
exp = "Manipulate[Plot[Sin[a x+b],{x,0,6}]," <> parameters <> "]";
ToExpression[exp]

"framework" that makes use of the Manipulate command, and which can be
used with several different types of parameters. Using one of the
examples from the documentation to illustrate my point:
