I have below for loop inside one apex method and here records i am passing as 3000 then it is hitting the heap limit and my code is not working as expected 

for(Integer i=0;i<recordsCount;i++){                
                Purchase_Request_Line_Item__c purchaseRequestLineItem = newPurchaseRequestLineItem.clone(false,true);
                String uniqueId= getUniqueId();
                Inventory_Item__c inventoryItemRecordReference = new Inventory_Item__c(PRLIExtID__c=uniqueId);
                purchaseRequestLineItem.Inventory_Item__r =inventoryItemRecordReference;
                SObject inventoryItemRecord = childObjRecord.clone(false, true);
                inventoryItemRecord.put('Name',inventoryItemRecord.get('Name')+'-'+String.valueOf(i)+' '+date.today().format());
                inventoryItemRecord.put('PRLIExtID__c',uniqueId);
                recordsToInsertInInventoryItem.add(inventoryItemRecord);
                recordsToInsertInPurchaseLine.add(purchaseRequestLineItem);
                if (math.mod(i, 1000) == 0) {
                    system.debug('Inside for: Heap size is ' + limits.getHeapSize() + ' enforced is ' + limits.getLimitHeapSize());
                }
            }
