Can WinSCP make a FTP secure, as our FTP Client doesn't support SFTP

We are using a Vision System that only supports FTP and our customer is insisting of SFTP. If we use WinSCP can we make the FTP Client to Sever connection secure.

I'm not sure I understand your question.

WinSCP supports SFTP, as well as a secure version of FTP, the FTPS (aka FTP over TLS/SSL). Is this what you ask for?
