Return all results in a grouped query even if the sum is zero or null

Question

I have the following consultation grouped:

SELECT 

SUM(SUC.PESO),
EXTRACT(DAY FROM HU.FIM),

CASE WHEN (ACO.COLUNA_2 IN ('L','C') AND HU.ESP_MM_UNMET<=3) THEN 'Carb' WHEN (ACO.COLUNA_2 IN ('L','C') 
AND HU.ESP_MM_UNMET>3) THEN 'Carb' WHEN (SUBSTR(ACO.COLUNA_1,1,3)='P39') THEN 'Duplex' WHEN (SUBSTR(ACO.COLUNA_1,1,2)='P3') THEN '3XX' 

WHEN (SUBSTR(ACO.COLUNA_1,1,2)='P2') THEN '3XX' 
WHEN (SUBSTR(ACO.COLUNA_1,1,2)='P4') THEN '4XX' 
WHEN (ACO.COD_IDENT_FMACO='GNO') THEN 'GNO' 
WHEN (SUBSTR(ACO.COLUNA_1,1,4)='P999') THEN 'GO'

This query returns me the sum of a database field with the following structure:

1º -> Sum of weight 2º -> Day of the sum 3º -> Product Type Group.

The problem is that I don’t have all the products in every day and so currently if I had the production of two products on the 1st it returns me the following result;

Product Weight Day

10000 1 3XX

56000 1 4XX

Only that I need the consultation always return all types of product, even if on the day it has not had production, for example on the first day it should return me:

Product Weight Day

10000 1 3XX

56000 1 4XX

0 1 Carb

0 1 Duplex

0 1 GNO

0 1 GO
