                            Is it imperative to apply the Vacuum Seal on the parting line?
                        
                                                    
                                Yes it is, otherwise the air that is being taken out from the cavity will be coming in from the parting line.
                            
                                                
                                                            
                            
                                                            
                            
                                                                                      
                            What is the maximum working temperature?
